[PR20402][LD][AARCH64]Don't emit RELATIVE relocation for absolute symbols which are resolved at static linking time.
For absolute symbols which are forced local or not dynamic, the ABS relocation
should be resolved at static linking time.
Originally, an RELATIVE/ABS relocation will be generated even for absolution
symbols for the dynamic linker to resolve.
