[PATCH, libsanitizer] Enable for PowerPC little endian


The upstream libsanitizer code has been modified to support powerpc64le-linux,
but we seemed to have forgot to enable it being built by default on LE.
I applied the patch below and ran the testsuite and the test results look
similar to the BE results, maybe even a little better.  I believe they
should look even better the next time we merge in the upstream ASAN code.
Ok for trunk?  ...and is this ok now or should it wait for stage1?
