[configure] Fix automake version check

The configure script fails on automake-1.11 (in Fedora-11) since
it looks for 3-digit version number.

"Yann E. MORIN", added the following comment:

The check for the automake version is not against a 3-digit number,
but really against a 3-part version number, a-la 'x.y.z'. Versions
such as 1.10 and 1.11 are also valid.

     2  The generated libtool for building libstdc++ adds the -nostdlib option to the
     3  g++ command for linking but doesn't add -lgcc.  This causes a "hidden symbol"
     4  error when linking against the libstdc++ shared object.  This patch adds gcc
     5  to the list of libraries linked against when linking libstdc++.
