[ Upstream commit 5c595ac4c776c44b5c59de22ab43b3fe256d9fbb ]
gcc-11 adds support for -fsanitize=kernel-hwaddress, so it becomes
possible to enable CONFIG_KASAN_SW_TAGS.
Unfortunately this fails to build at the moment, because the
corresponding command line arguments use llvm specific syntax.
Change it to use the cc-param macro instead, which works on both clang
and gcc.
