You need the userspace headers for 64-bits. They don't exist, so I
normally hack them into place. Please try to use Kegel's crosstools and
see if you can get them building our cross-compiler? :)

If you want a quick fix, grab a current debian libc6-dev package, unpack
it using -x and move the /usr/include directory to your
$PREFIX/hppa64-linux directory so that the target headers are there.
