kpatch-build: clang support Add support for clang-built kernels. This is completely automatic, we check if the kernel was built with clang by looking for CONFIG_CC_IS_CLANG in config. This has almost no effect on non-clang built kernels with one exception: we now do compliler checks _after_ we download kernel sources which is a waste of resources in case when compilers don't match.

--skip-compiler-check
Skips check that ensures that the system compiler version and
the compiler version that built the kernel match. Skipping this
check is not recommended, but is useful if the exact compiler
Allow user to skip gcc version check Right now, unless the entire gcc version string, including build date and package version, matches the distro kernel exactly, kpatch-build won't proceed. For some distros, it is very difficult to rollback to a previous version of gcc and keep that version pinned on the system so that the package manager doesn't update it. For these user, add a --skip-gcc-check flag to kpatch-build to allow the version check to be skipped. If the user does this, it is assumed they know what they are doing. This flag is documented as "not recommended". Signed-off-by: Seth Jennings <sjenning@redhat.com>
