This code is not really used by linux except for embedded. The real version
should be in sysdeps/powerpc/powerpc32/fpu/

The original fpu/__longjmp.S had the appropriate PIC implementation.

not sure where sysdeps/powerpc/powerpc32/____longjmp_chk.S can from or what
you did build it versus sysdeps/powerpc/powerpc32/fpu/____longjmp_chk.S Of
is that missing?
