AIX 64-bit patches from Steven Hirsch <hirschs@btv.ibm.com>

The patch to File/Glob/Makefile.PL is inconvenient but at the
moment necessary: adding an ext/FIle/Glob/hints/aix.pl to turn
off the optimization ($self->{OPTIMIZE} = '') doesn't work,
the file is processed by MakeMaker but OPTIMIZE ends up as -O
in the resulting Makefile.  A MakeMaker bug?
