rpm: Fix autoconf/libtool usage

In order to resolve a host-contamination problem, we re-work the way that
autoconf and friends are invoked during the compilation of RPM.

This has a side effect of fixing another bug where RPM was being renamed
HOST_ARCH-HOST_OS-rpm.  So we remove the "fixes" for that behavior as well.
