There appears to be a problem with putting this stuff under sysdeps/sparc/nptl,
in that header files under nptl/sysdeps/unix/sysv/linux/ will be choosen first.

As a result, sysdeps/sparc/nptl/internaltypes.h won't be used, instead we end up
using nptl/sysdeps/unix/sysv/linux/internaltypes.h.

This leads to the build failing:

../sysdeps/sparc/nptl/pthread_barrier_destroy.c: In function ‘pthread_barrier_destroy’:
../sysdeps/sparc/nptl/pthread_barrier_destroy.c:32:25: error: dereferencing pointer to incomplete type
 ...

etc.

I can't think of an easy way to fix this.
