[Buildroot] [git commit] package/gcc: disable libsanitizer for uClibc

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=554e29e267e6b36a0fd78c82cbad2c82d939eb7f
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

libsanitizer requires wordexp() support which we lack in our current
default uClibc configurations (and it's fat & big).
Hence disable it when the toolchain is uClibc-based.
It only affects gcc 4.9+ since it's default on now for supported
platforms.
