[gentoo-releng] NPTL and 2006.0

Alright, so I'm guessing that we're going with NPTL for 2006.0, except
on arches where the arch team has determined that it isn't stable, or
that doesn't have a stable 2.6 headers/kernels.

Here's what I've done for x86, and I really encourage all of you to
follow suit.

I've created a no-nptl sub-profile that has "nptl nptlonly" in use.mask,
along with a 2.4 sub-profile.  This 2.4 sub-profile will be *the* 2.4
sub-profile for x86, with the other 2.4 profiles being deprecated.  I
have added "nptl" to USE for the 2006.0 profile, and *not* for the "x86"
profile.  Also, because x86 supports 2.4-based systems, I have *not*
added STAGE1_USE="nptl".  If your architecture is on 2.6-only, then you
are free to add this to your profile.  I highly recommend *against*
adding nptlonly to STAGE1_USE or USE at this time.  I have also
minimized the USE flags enabled in the default-linux/x86 profile.  This
makes the profile very usable for non-release sub-profiles, by limiting
the number of USE someone is forced to disable.  All of the other USE
flags are enabled in the sub-profiles for each release.

So... there's my "lead by example" so much as it applies.  Feel free to
make any arch-specific changes you wish to your own profiles, but I've
given you what I plan on doing on x86 for the future.
