Revert "Fix bootstrap to work where aclocal is..."

This reverts commit f12fbe8.

I just observed how preferring of 1.10 over 1.12 caused innocent
people pain.

Lack of forward-compatibility in this entire approach of preferring
some specific version over canonical one is evident and should not be
accepted.

Users who want some extra costumizations can do it by setting right
environment variables or by implementing shell wrappers.
