Not append rela for absolute symbol
LoongArch: Not append rela for absolute symbol
Use la.global to get absolute symbol like la.abs.
la.global put address of a global symbol into a got
entry and append a rela for it, which will be used
to relocate by dynamic linker. Dynamic linker should
not relocate for got entry of absolute symbol as it
stores symval not symbol's address.
