[git commit prelink] bfin: fix fp reference in _JMPBUF_UNWINDS

[Mike Frysinger]

commit: http://git.uclibc.org/uClibc/commit/?id=9112a2398ec58b32cd1a1c6feae195bd8f9a46a2
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/prelink

We want to access the frame pointer, so do so directly rather than
"overflowing" the pregs array and ending up at the fp member.

This fixes the Blackfin build warnings:
libpthread/linuxthreads.old/ptlongjmp.c: In function 'pthread_cleanup_upto':
libpthread/linuxthreads.old/ptlongjmp.c:35: warning: array subscript is above array bounds
libpthread/linuxthreads.old/ptlongjmp.c:56: warning: array subscript is above array bounds
