[Buildroot] [PATCH] uclibc-ng: remove temporary workaround

[Waldemar Brodkorb]

fminf and others got implemented in the time after this
patch was added. Remove the workaround to get mesa compiled
with uClibc-ng.

Signed-off-by: Waldemar Brodkorb <wbx at openadk.org>

Patch from git branch of uClibc-ng.
So no upstream action required, will be in 1.0.3.
