Hi!
This is what I had to apply to make glibc build on alpha.
There are still many testsuite failures, but they all seem to be unrelated to
this (lots of regex tests failed (which work on all other arches and there
is nothing arch specific about that, maybe b0rken compiler), some math
test failures, backtrace failures, 2 aio failures).
Richard, I hope doing jsr ra, __errno_location is the right thing to do
for librt.so (__errno_location symbol is defined only in libc.so and
libpthread.so, not in librt.so, so it can't be !samegp).
I was testing this on a kernel without POSIX mq support, so this
hunk probably did not get as much testing as it ought to.

* sysdeps/unix/alpha/sysdep.h (inline_syscall6): Fix a typo.
[BZ #231]
* sysdeps/unix/alpha/sysdep.S (__syscall_error): Avoid !samegp
relocation in librt.so.
[BZ #230]
* sysdeps/alpha/dl-machine.h (_dl_start_user): Use ldah/ldl to load
_dl_skip_args. Patch by Jakub Bogusz <qboosh@pld-linux.org>.
nptl/
* sysdeps/alpha/tcb-offsets.sym (MULTIPLE_THREADS_OFFSET): Define
unconditionally.

Applied. If something can be improved rth will hopefully let us know.
