tools/automake: use make variable to generate aclocal symlinks

Instead of having a somewhat random list of aclocal symlinks
which are named with the API versioning scheme,
install a symlink for every API version since 1.11
(the first release after Automake was moved to git)
using the API version number from the version of automake
that is currently in openwrt.

Automake API versioning does not include the patch level number.
