- USE_AUTOTOOLS contains aclocal but not autoconf which leaves configure

out of date and causes make (build phase) to run autoconf, erasing any
  configure patches.  Then make reruns configure.  Instead of adding
  autoconf to USE_AUTOTOOLS avoid USE_AUTOTOOLS altogether by patching
  Makefile.in instead of Makefile.am.
- Use INSTALL_TARGET=install-strip and USES=pathfix
