[PATCH] Fixing sh4 and sparc builds.

[Rob Landley]

I needed the following patch to make sh4 and sparc build with 
pthreads.old in current git:

 # check weather __LONG_DOUBLE_128__ is defined (long double support)

I also had to symlink:

  ln -s ../../../linuxthreads/sysdeps/pthread/tcb-offsets.h libpthread/linuxthreads.old/sysdeps/pthread/tcb-offsets.h

Because you only have that link in the new pthreads and the sparc build breaks looking for it on the old one.
