In D116573, the relocation behavior of R_RISCV_BRANCH didn't consider that branch instruction like 'bge' has a branch target address which is given as a PC-relative offset, sign-extend and multiplied by 2.
Although the target address is a 12-bits number, acctually its range is [-4096, 4094].
This patch fix it.
