Remove a fudge from tc-ppc.c:md_apply_fix3

[Geoff Keating]

The way I'd look at this patch is this:

1. Does the patch actually fix any known bug?
2. Can you write a testsuite that exercises all the code paths that
   the patch affects?

If the answer to both questions is 'no', the patch is all risk and no
reward, and so there's no point committing it.

Just testing GCC and glibc is not enough.  There are a bunch of other
special cases that are difficult to list.  At a minimum, you need to
install the resulting glibc and run 'make check-ld' and 'make
check-gcc RUNTESTFLAGS=--target_board=unix/{,-fpic,-fPIC}'.  Even that
won't cover the weirder cases.
