[git commit] test/silly: Extend include path.

[Bernhard Reutner-Fischer]

commit: http://git.uclibc.org/uClibc/commit/?id=ec0827d3c2af5c9569c04cbb6f57a3c581583722
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

When attempting to build uClibc under buildroot, including building the
tests, the silly tests don't currently compile, a result of attempting
to build using a compiler that does not yet have an installed version of
uClibc available.  The error is a missing header file, specifically
atomic.h.

Taking inspiration from the nptl tests, I have extended the EXTRA_CFLAGS
variable to add the required include paths.  The tests can now be built
under buildroot.
