binutils: don't discard eh_frames during ld -r
We don't have enough information to decide whether or not to discard them
until relative addresses are worked out, i.e. at the final link.

binutils: rework jump pseudoisntruction
"jump" was renamed to "tail" (as in tail call) and may freely clobber a
t-register, as before. A new "jump" was added that requires a second
argument, which is the scratch register it may clobber.
"tail" should be used for tail calls; "jump" should be used for
intraprocedural jumps more than 1 MiB away.

gcc: Fix 64 bit multiply on RV32.
Use define_expand instead of define_insn_and_split for 64-bit
multiply on RV32. With define_insn_and_split, gcc would occasionally
overwrite a source register in the first instruction of a mulhu/mul
pair.

binutils, glibc: avoid DT_TEXTREL in ld.so
ld.so was using a non-PIC reloc to get the link-time address of _DYNAMIC,
which, while correct, causes the library to be flagged DT_TEXTREL. Avoid
this by leveraging the fact that the static linker has put the link-time
address of _DYNAMIC in the first GOT entry.

Disable "-Werror" during binutils builds
Some shared binutils source code throws some harmless looking errors
with newer GCC versions. This patch stops failing the binutils build
whenever these errors show up.
Both Gentoo and LFS set this flag, so I think it's sane.

binutils: support code alignment in the linker
We over-emit NOPs in the assembler, then delete them in the linker to achieve
the required alignment. This allows alignment to work in spite of other
linker relaxations.

binutils: fix (?) relaxation symbol adjustment
I think there were a few off-by-one errors. If so, they exist in other

binutils: favor elfnn-riscv.c over elfxx-riscv.c
Since a lot of code is dependent on the word size, it's both simpler and
more efficient to put that code in elfnn-riscv.c. Only code that does not
depend on the word size remains in elfxx-riscv.c.
