[Buildroot] [PATCH] uclibc: respect top-level TARGET_CFLAGS

[Alexey Brodkin]

When BR2_TARGET_OPTIMIZATION is used (with some specific compiler flags)
it's expected that ALL target binaries will be built with specified options.

Currently uClibc is built with its own set of options.
This change allows passing additional flags to uclibc build system.
