Sorry, I didn't realize you were talking about "-Wno-error" literally.
This may break non-gcc compilers.  It would be better to come up with
an $(INTERNAL_CFLAGS) variant that does not include -Werror in the first
place, and use that instead in the memmem.o rule.  gdb/Makefile.in uses
INTERNAL_WARN_CFLAGS for exactly that.  I suggest to do the same here.  Take
a look at the monitor.o rule in gdb/Makefile.in.
