[Buildroot] [PATCH 1/2] uclibc: unbreak SH & SPARC

[Gustavo Zacarias]

The patch from commit 200aad4f3206c9f151f15922dd02b01f474a5503 broke sh
and sparc builds.
Add and adjust a patch from uClibc master that fixes this.

Applied, thanks.

Waldemar, is this patch also needed for uClibc-ng ?

Thanks,

1.0.1 didn't have the offending patch applied, and 1.0.2 already
includes it, so no need to touch anything for -ng.
