Add in version dependency checks on all the tools we depend on. This is

necessary to ensure that a consistent configuration is created on each
platform. Certain definitions we use (like m4/libtool.m4) require certain
versions of the tools and we can no longer be slack about this or we'll
have problems with mis-configured builds.
