uClibc-ng does not support PIE for some architectures as
arc and m68k. It isn't implemented in the static linking case, too.
With musl toolchains you might have static PIE support with little
patching of gcc. Static linking for GNU libc isn't enabled in
buildroot. Fixup any package using special treatment of PIE.

Even though ARC gcc understands "-pie" option and attempts to generate
PIE binaries as of today PIE is not really supported for user-space
applications.
So we disable PIE detection if building for ARC.
That fixes http://autobuild.buildroot.net/results/be4/be46b621ce5443788b0a1bc9fab614c4ca5d0859
and also prevents execution of non-supported PIE binary in runtime.
