toolchain/gcc: remove uclibc hack

This was introduced with 014d3b98b96872d020ffccf0358ba60967b3f1c0 , which
is almost 10 years old. uClibc-ng does not suffer from this problem.

Note that this hack prevents libstdc++ from using C++11 math functions.

Tested by removing all of the mpd patches designed to fix this and
compiling.
