Build fails with build-many-glibcs.py script and target hppa-linux-gnu.

[Stefan Liebler]

Hi,

I've run build-many-glibcs.py script and recognized that the build fails 
for target hppa-linux-gnu due to fails like the following:
hppa-glibc-linux-gnu-gcc old_pthread_cond_init.c -c ...

The build succeeded before commit 
ed19993b5b0d05d62cc883571519a67dae481a14 "New condvar implementation 
that provides stronger ordering guarantees.".
It seems that at least the required changes in pthreadtypes.h are 
missing for hppa.
Torvald, can you please have a look at it?

Bye.
