I'd forgotten about the extra-patches patch.   I wonder if it would make
the people happy who have been asking for a site-patches directory...

OK.

Not ok.  You can build gcc/glibc with TLS fine with plain old
crosstool (I just did it recently), but to build with NPTL support
you need to go out on a limb and apply another patch to
crosstool (which builds the compiler again, as you mentioned).

An NPTL patch for 0.42 is here:
http://sourceware.org/ml/crossgcc/2006-03/msg00090.html
0.38 probably has an NPTL patch in contrib, or there
may be a more up-to-date one in the crossgcc archives.

NPTL is still somewhat rocket science.  I haven't tried it myself
so there may be bats in the belfry yet.
