Things like PYTHON_TARGETS, X86_ABI and VIDEO_CARDS are implemented as
USE variables, so yes, -* clobbers them too.

A lot more complicated if you have to follow a mailing list just to keep
your system working. You have essentially put your system into a
firefighting mode where you have to deal with each change as it breaks
things. The real problems occur when the cause of the issue that you are
suffering is not clear, and others cannot help because they use a profile
so do not experience it.

If you comment out your USE line and run "emerge --changed-use -p
@world" (do not use -v!) you will see what you actually need to set. Then
you can ad those to make.conf or package.use. It may take you half an
hour, but you'll end up with a system that maintains itself to a greater
extent.
