The magic happens in the toplevel Makefile, which is not installed in
kbuild:
| ifdef CONFIG_FUNCTION_TRACER
| KBUILD_CFLAGS += -pg
| ifdef CONFIG_DYNAMIC_FTRACE
| ifdef CONFIG_HAVE_C_RECORDMCOUNT
| BUILD_C_RECORDMCOUNT := y
| export BUILD_C_RECORDMCOUNT
| endif
| endif
| endif
In scripts/Makefile.build the behavior depends on the
BUILD_C_RECORDMOUNT setting.
| ifdef CONFIG_FTRACE_MCOUNT_RECORD
[...]
| cmd_record_mcount = \
| if [ "$(findstring -pg,$(_c_flags))" = "-pg" ]; then \
| $(sub_cmd_record_mcount) \
| fi;
| endif
So the patch I sent might happen to work. Here's a presumably better
patch (still untested).
