Some targets don't have a PC relative relocation of pointer size, e.g. `R_MIPS_PC64` (MIPS only has `R_MIPS_PC32`, which is a GNU extension, sigh https://sourceware.org/git/?p=binutils-gdb.git;a=commit;f=include/elf/mips.h;h=092dcd755dcdcf664b25a7011fd15957f124c29f). If we really need a PC-relative variant, we can use a new syntax `-fpatchable-function-entry=2,0,pcrel` with the existing option name. Let me commit the patch series.
