Yes, but there are reasons why this is not exactly a good idea. Not
all Makefile.am constructs work the same with all versions of automake,
and for those who do, it is up to the upstream to allow or disallow them
in the bootstrap script. Something along these lines:
if automake-1.9 --version >/dev/null 2>&1; then
elif automake-1.8 --version >/dev/null 2>&1; then
echo "No supported automake version"
Blindly calling "automake" instead of a specific version is one
of the wrong reasons people think the autotools constantly break
