Don't use "_gp" on RISC-V, use "_global_pointer$" instead
"_gp" could conflict with ABI-complient code. While it's probably OK
because MIPS uses this name, we figured it'd be good to clean this up
before a release with RISC-V in it.
ld/ChangeLog:
2017-02-13 Palmer Dabbelt <palmer@dabbelt.com>
* emulparams/elf32lriscv-defs.sh (SDATA_START_SYMBOLS): Change
_gp to __global_pointer$.
bfd/ChangeLog:

* elfnn-riscv.c (riscv_global_pointer_value): Change _gp to
__global_pointer$.
