I didn't get that quite right. 'powerpc*' in the above matches too
much, for example when your host is powerpc64-linux and target
powerpc64le-linux you'll get -melf64ppc added to LD. Since
powerpc64le-linux-ld wants -melf64lppc (or nothing) that will fail.
Revised as follows.
* m4/libtool.m4 (ld -m flags): Remove non-canonical ppc host match.
Support little-endian powerpc linux host.
