MIPS: Use pcrel|sdata4 for eh_frame (#91291) Gas uses encoding DW_EH_PE_absptr for PIC, and gnu ld converts it to DW_EH_PE_sdata4|DW_EH_PE_pcrel. LLD doesn't have this workarounding, thus complains ``` relocation R_MIPS_32 cannot be used against local symbol; recompile with -fPIC relocation R_MIPS_64 cannot be used against local symbol; recompile with -fPIC ``` So, let's generates asm/obj files with `DW_EH_PE_sdata4|DW_EH_PE_pcrel` encoding. In fact, GNU ld supports such OBJs well. For N64, maybe we should use sdata8, while GNU ld doesn't support it well, and in fact sdata4 is enough now. So we just ignore the `Large` for `MCObjectFileInfo::initELFMCObjectFileInfo`. Maybe we should switch back to sdata8 once GNU LD supports it well. Fixes: #58377.
