Make Makefile's test programs safe(r)
We don't use -W or similarly strict compiler checks (yet), but enabling its use is a good thing. if you add -W to the cflags without this patch, detection of the compiler will fail with gcc 4.4 for example, because compiling of the test program will fail due to a warning of unused arguments and -Werror. similarly the other checks involving compiling test programs would fail. Corresponding to flashrom svn r1356. Signed-off-by: Stefan Tauner <stefan.tauner@alumni.tuwien.ac.at> Acked-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net>
