libc/glibc: fix cross-compiling to i686

In OE-lite we use the attached patch for building i686 cross compilers.
Thanks to Khem Raj for original patch :-)

At the same time, remove the corresponding patch that was in
the ports patchset.

If gcc is configured to generate i686 code or better by default (like
when using the --with-arch=pentium3 configure option), then the __i686
macro will always be defined automatically and thus screw up the
compilation of some .S files.
