riscv: Fix incorrect jal with HIDDEN_JUMPTARGET
A non-local STV_DEFAULT defined symbol is by default preemptible in a shared object. j/jal cannot target a preemptible symbol. On other architectures, such a jump instruction either causes PLT [BZ #18822], or if short-ranged, sometimes rejected by the linker (but not by GNU ld's riscv port [ld PR/28509]). Use HIDDEN_JUMPTARGET to target a non-preemptible symbol instead. With this patch, ld.so and libc.so can be linked with LLD if source files are compiled/assembled with -mno-relax/-Wa,-mno-relax.
