a fix for hung build on HP-UX 11.11

On HP-UX 11.11, gcc build hangs. $(SHLIB_MAPFILES) is empty, cat with empty
imput tries to read stdin and that results in the hang. I'm attaching a patch
to fix the problem.

I assume this is with HP cat.

Suggest posting patch to gcc-patches.  CC me.  If accepted, I will
apply.

I have just encountered it with 4.8.0. Instead of adding /dev/null, I have
changed
ifneq ($(SHLIB_MKMAP),)
to
ifneq ($(SHLIB_MAPFILES),)
I'm not sure if it doesn't break anything, though, as in my case the resulting
libgcc.map isn't created at all. The build completed anyway, and the resulting
GCC seems to be working fine, though.

It looks as if SHLIB_MAPFILES needs to be defined.

Should be fixed with this commit:

Don't know why the normal commit messages aren't showing up.
