[libvirt] [PATCH] maint: the compiler is not always named gcc

https://bugzilla.redhat.com/show_bug.cgi?id=994589 complained that even when using a cross-compiler not named 'gcc', the configure output confusingly referred to gcc. * m4/virt-compile-warnings.m4 (LIBVIRT_COMPILE_WARNINGS): Use a more generic statement in configure output.
