Makefile.uk: Fix unsupported warnings when built with clang

Clang (12.0.0) does not recognize the warnings: no-unused-but-set-variable no-maybe-uninitialized no-builtin-declaration-mismatch It would print "unknown warning option" warning messages. These should be enabled only with GCC (tested with 11.3.0).
