binutils-gdb/bfd/elfxx-loongarch.c
liuzhensong 9801120721 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.
