    PowerPC: incorrect library search order
    
    First, need to match against just the CPU name, not the whole triplet.
    Otherwise, the test picks up "*le-*" pattern from x86_64-apple-darwin
    triplet.
    
    Second, it should be testing for $target, not $host. Host may be
    little endian by default, and the sysroot directory layout shouldn't
    depend on whether it is built on LE or BE machine.
    
    	* emulparams/elf32ppccommon.sh (LIBPATH_SUFFIX): Set from target
    	cpu, not host.
