Be prepared to screw up your system. Installing glibc manually is not
for the faint of heart.
If you compile out of the box, you will get 32bit binaries. You do not
even want to mess with 64bit unless you are absolutely sure you know
what the heck you are doing.
You can always install libc6-dev-sparc64 and gcc-3.0 to get 64bit
development environment (just set CC="gcc-3.0 -m64" for compiles).
If you really want to know more about this, add some deb-src lines (or
download directly) and do "apt-get source glibc", and check out all the
build stuff in debian/*. Yes, there's a lot there, but you didn't expect
it to be simple, right? :)
