This debian patch takes no effect.

Actually it try to fix this:

Some packages which has those lines in Makefile.PL:
   WriteMakefile(
       ...
       'CCFLAGS'    => 'some cflags',
       ...
   );
While run perl Makefile.PL to configure, there are CCFLAGS="some cflags" 
to override the original CCFLAGS=$Config{ccflags} in generated Makefiles.


In Poky, CCFLAGS in our generated Makefiles are all right.
But when we run oe_runmake CCFLAGS="${CFLAGS}" to do_compile, this will 
override our right CCFLAGS.
