Subject: [PATCH] Allow "versioned" names of the auto-tools to be used.

Previously bootstrap required aclocal/automake to be available as
"aclocal" and "automake", but some platforms allows multiple versions
of these tools to be installed and makes them available as
"aclocal-<version>".

This patch extends the bootstrap script to try to search for various
names for the tools.

Patch by Trond Norbye.
