perf build: Remove FEATURE_CHECK_LDFLAGS-disassembler-{four-args,init-styled} setting

perf build: Remove FEATURE_CHECK_LDFLAGS-disassembler-{four-args,init-styled} setting

As the building mechanism is now able to retry detection with different
combinations of linking flags, setting FEATURE_CHECK_LDFLAGS-disassembler-four-args
and FEATURE_CHECK_LDFLAGS-disassembler-init-styled is not necessary anymore,
so remove it.

James Clark notes:

Use the same technique to find the set of bfd-related libraries to link as in:
