In tools/perf/Makefile:

34:# Define WERROR=0 to disable treating any warnings as errors.
69:ifneq ($(WERROR),0)
70:     CFLAGS_WERROR := -Werror
105:CFLAGS = -fno-omit-frame-pointer -ggdb3 -Wall -Wextra -std=gnu99 $(CFLAGS_WERROR) $(CFLAGS_OPTIMIZE) -D_FORTIFY_SOURCE=2 $(EXTRA_WARNINGS) $(EXTRA_CFLAGS)

This Makefile _only_ applies to the perf tools.  The rest of the kernel
uses other Makefiles.

The perf tools are not built automatically, so if you are only trying to
build a kernel image then you must have some other problem.


As I suggested previously, can you please run

make V=1

and send the last few lines of output, including the error message *and*
the command which caused it.

Without a precise indication of where the error occurs, I can't offer much
help.
