Probably a kludge to get around some build problem.  I don't
think crosstool suffers from that kind of problem, since
in crosstool the building of gcc and glibc are carefully
orchestrated.

It failed when building gcc-3.3.3 with glibc-2.1.3, so I
looked at what it did, and it turned out to be a big hammer
to override the careful autodetection libstdc++ does
on the c library's locale support.  So it's a bad
thing to do in general unless you're quite, quite sure
you need it.

Yes, though there's some chance the data might be portable you can build it
on one architecture and copy it to another.  I don't know.
Anyway, it's not something that's automatable right now
without a fair bit of work to understand the issues.
