Multiple issues fixed: - module was compiled against `uname -r` kernel, not eselect-ed one - released version requires a patch to compile with Clang - previous attempt to forward CC to fix Clang compilation was incorrect from every standpoint; e. g. it there is KERNEL_CC for that, etc. Removed it, as upstream now has proper support (backported via patch). Closes: https://bugs.gentoo.org/973282 Signed-off-by: Sv. Lockal <lockalsash@gmail.com>
