glibc: Use riscv.*- for shlib-versions CPU pattern
This fixes inconsistent symbol versioning with shared libraries when the
target machine is specified as `riscv64' instead of `riscv'.

glibc: handle negative syscall results properly
Not all are errors; they may just be large values.
Only results in the range [-4095,-1] are errors.

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.
