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.

gcc/ChangeLog:

	* config/loongarch/loongarch.h (ASM_PREFERRED_EH_DATA_FORMAT):
	Modify the definition of the ASM_PREFERRED_EH_DATA_FORMAT macro.
