[OE-core] [PATCH 2/3] autoconf: Remove code checking for hardcoded /usr/local

[Khem Raj]

This code is only relevant for AIX and causes
problems with OE QA sniffer which detects -L/usr/local/lib
on linker commandline during cross compile and rightly barfs

This only happens when getloadavg() is not found in libc
so we do not reach that code with eglibc but only with uclibc

+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.
