Isn't the added COMPILER_VERSION comparison in reverse?

I thinl the option "-Wno-address-of-packed-member" is to suppress
the exact error, not to activate the check.

And another thing I've noticed (but not 100% sure which is correct).

Manually editing ${WRKSRC}/i915/Makefile after `make patch` with
.if ${COMPILER_TYPE} == clang && ${COMPILER_VERSION} < 211
allows following `make` to finish successfully on stable/15.
(Possibly "<=" instead of "<" is correct, though.)

The modified code compares COMPILER_VERSION >= 211, while existing
graphics/drm-66-kmod/files/patch-i915_Makefile has comparison as below. As seen
in the patch, comparing with 210000, not 210.
