RISC-V: Don't generate branch/jump relocation if symbol is local when no-relax.
Refer to commit, dff565fcca8137954d6ad571ef39f6aec5c0429c. Theoretically,
assembler don't need to generate the pc-relative relocation and the refered
local .L symbol when relaxation is disabled. The above commit improved the
pcrel_hi/pcrel_lo relocations, and this commit improves branch and jump
relocations.
Passed the gcc/binutils regressions of riscv-gnu-toolchain.
gas/
* config/tc-riscv.c (md_apply_fix): Raise fixP->fx_done for all
branch and jump relocations when -mno-relax.
