I think that the same thing needs to happen in gcc-sanitizers.inc,
otherwise I get errors like:

| .../recipe-sysroot/usr/include/gpg-error-64.h:884:11: fatal error: sanitizer/lsan_interface.h: No such file or directory

when attempting to compile with sanitizers enabled.

FILES_${PN} needs updating to match too.
