The spec does not forbid the misaligned memory access. And the gcc
will generate vector load/store to access misaligned memory by
default.
Currently the QEMU supports this feature, so to support in spike
is also make sense.
Reference test case: gcc/gcc/testsuite/gcc.dg/vect/vect-align-1.c
Some glibc tests like tst-unwind-{main,ctor} depends on stage2 artifacts
(in particular, GCC runtime libs) to be properly installed. Add stage2
dependencies to avoid these tests from spuriously failing.
The test suite also uses the simulator and Deja GNU, both of which were
not declared as dependencies, so add them as well.

pyelftools is required for a helper script.
This commit adds basic installation guide to install pyelftools and
removes "automatic installation" of pyelftools from Makefile.
Due to multiple accidents while releasing GNU Binutils, version 2.41,
there are multiple tags that are broken.
The true commit representing the version 2.41 of GNU Binutils is
the head of `binutils-2_41-release-point` branch.
This commit partially reverts commit c7853bf388.
This patch allows you provide the flags in build flags array acts on arch-abi
__respectively__, you can use ',' to separate them. For example:
`rv64gcv-lp64d:--param=riscv-autovec-lmul=dynamic,--param=riscv-autovec-preference=fixed-vlmax`
will be consider as two target boards same as below:
```
riscv-sim/-march=rv64gcv/-mabi=lp64d/-mcmodel=medlow/--param=riscv-autovec-preference=fixed-vlmax
riscv-sim/-march=rv64gcv/-mabi=lp64d/-mcmodel=medlow/--param=riscv-autovec-lmul=dynamic
```
However, you can also leverage AND(`:`), OR(`,`) operator together but the
OR(`,`) will always have the higher priority. For example:
`rv64gcv-lp64d:--param=riscv-autovec-lmul=dynamic:--param=riscv-autovec-preference=fixed-vlmax,--param=riscv-autovec-lmul=m2`
will be consider as tow target boars same as below:
```
riscv-sim/-march=rv64gcv/-mabi=lp64d/-mcmodel=medlow/--param=riscv-autovec-lmul=dynamic/--param=riscv-autovec-preference=fixed-vlmax
riscv-sim/-march=rv64gcv/-mabi=lp64d/-mcmodel=medlow/--param=riscv-autovec-lmul=m2
```

This patch imports the Linux kernel from v5.10.5 to v6.6.
Important RISC-V specific changes are:
* hwprobe support
* V support (ptrace and prctl calls)
* KVM support
There are patches on the glibc list that introduce code which uses the
hwprobe interface. Let's update the kernel headers to be ready for these
changes.

As we have quotes surround the argument already, it is unnecessary
to ESC `;` to `\;` due to the `;` has special meanings in shell.

* Refactor CPU options for exacting common part between qemu and spike.
* Inject CPU options to spike run command line.
The below common CPU options are extracted to common part.
* xlen
* vlen
* extensions
The above CPU options will be leveraged to build the run arguments for
both the qemu and spike, for example.
QEMU: qemu-riscv64 -cpu rv64,v=true,vlen=1024,elen=64,vext_spec=v1.0
SPIKE: spike --isa=rv64imafdcv_zicsr_zifencei_zmmul --varch=vlen:1024,elen:64

Recently we have add the capability to adding extra compilation options
for running GCC testsuite, but it seems not handle well on the `make report`
part, it will ignore extra compilation options, and then...combine
multiple report together.
Now it will put in two different line, and the extra compilation options
will listed in follwoing line, here is example output here:
========= Summary of gcc testsuite =========
| # of unexpected case / # of unique unexpected case
| gcc | g++ | gfortran |
rv64gc_zicfilp_zicfiss/ lp64d/ medlow |20350 / 3967 |10158 / 2583 |18374 / 3098 |
rv64gc_zicfilp_zicfiss/ lp64d/ medlow | 86 / 19 | 15 / 9 | 51 / 51 |

The `--with-extra-multilib-test` take the format like below for now.
"<arch>-<abi>-[code-model][;<arch>-<abi>-[code-model]*"
This patch would like to extend the sematic to support additional buil
options for each combination. Aka:
"<arch>-<abi>-[code-model][:opts]*[;<arch>-<abi>-[code-model][:opts]*]*"
opts can be one or more build options splited by ':'. For example as
below:
* --param=riscv-autovec-lmul=m1
* --param=riscv-autovec-lmul=dynamic:--param=riscv-autovec-preference=fixed-vlmax
Thus the full example of the option `--with-extra-multilib-test` will be:
`rv64gcv_zvl128b-lp64d:--param=riscv-autovec-lmul=m1;rv64gcv_zvl256b-lp64d:-
-param=riscv-autovec-lmul=dynamic:--param=riscv-autovec-preference=fixed-vlmax`

Some testcases in GCC's testsuite check stdout.
Qemu will print a warning if the vector spec is not specified which will cause those testcases to fail.
The warning:
vector version is not specified, use the default value v1.0
