The tools build system uses KBUILD_HOSTCFLAGS symbol for obvious purposes. However this is not set for anything under tools/ As such, host tools apps built have no compiler warnings enabled. Declare HOSTCFLAGS for perf tools build, and also use that symbol in declaration of host_c_flags. HOSTCFLAGS comes from EXTRA_WARNINGS, which is independent of target platform/arch warning flags.
