We rebuild the Fedora kernel for CentOS with only a few changes (mainly
for armhfp).
Some of those changes may be part of Fedora, since they don't affect the
build process.
disable_headers_fedora_only.patch: Fedora builds kernel-headers
separately, do this only for fedora.
make_buildflags_optional.patch: build_cflags and build_ldflags are not
available in el7, make them optional.
Thanks.
