bfd: Delete R_LARCH_NONE from dyn info of LoongArch.
Some R_LARCH_64 in section .eh_frame will to generate R_LARCH_NONE, we change relocation to R_LARCH_32_PCREL from R_LARCH_64 in setction .eh_frame and not generate dynamic relocation for R_LARCH_32_PCREL. Add New relocate type R_LARCH_32_PCREL for .eh_frame. include/elf/ loongarch.h bfd/ bfd/bfd-in2.h libbfd.h reloc.c elfxx-loongarch.c elfnn-loongarch.c gas/config/ tc-loongarch.c binutils/ readelf.c ld/testsuite/ld-elf/ eh5.d
