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: 2017-02-13 Palmer Dabbelt <palmer@dabbelt.com> * elfnn-riscv.c (riscv_global_pointer_value): Change _gp to __global_pointer$.
