[gentoo-alt] masking useflag for prefix in an overlay

[François Bissey]

Hi,

I have at least one ebuild in an overlay that I try to maintain as
prefix friendly as possible. I have discovered that one of the ebuild
we carry has a useflag that is not working properly on macos-x86
(at least on 10.5.8). So I proceeded to mask it in:
profiles/prefix/darwin/macos/arch/x86/package.use.mask
However once I synced the overlay on my Mac the useflag was still
available for that ebuild.

Am I doing something wrong or are the overlays not inheriting that part of
the profile?
