coreutils: Fix build on uclibc

coreutils has getloadavg.m4 of its own. So we need
to make sure that we remove the portions which look
into hardcoded /usr/local/lib paths. These tests are
only for AIX so we dont lose much

+We have problem using hardcoded directories like /usr/local here
+which will be checked for cross builds. This is a special case which
+is valid for AIX only. We do not have AIX as one of our supported
+build host or target. Therefore we get rid of the hardcoded paths
+and make life easier for cross compilation process.
