[PATCH] MIPS/GCC: Unconditional jump generation bug fix

Hi, This was lost in the original microMIPS submission. For absolute microMIPS jumps GCC always produces a branch instruction, causing a `relocation truncated to fit: R_MICROMIPS_PC16_S1' linker error if the branch target turns out of range. The TARGET_ABICALLS_PIC2 macro is never set in ab
