[Buildroot] [PATCH] gcc 4.2.4: Fix builds for i686 when headers are not present.

[Khem Raj <raj.khem@gmail.com>]

with this I could reproduce this issue. Here is a patch for gcc
that will get you over this hump drop it into toolchain/gcc/4.2.4/
and rebuild the first problem will be ok. The problem with locales
is a separate issue and is not related to the toolchain build
sequence change.

If this works Then consider applying this patch to BR
