[PATCH 3/4] perf: Remove FEATURE_CHECK_LDFLAGS-disassembler-four-args

From: Roberto Sassu
Date: Tue Jul 19 2022 - 13:06:31 EST


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