Makefile.am fixes

Two problems.
1) skill/snice : distribution doesnt mean install
If you don't set your configure flags right, you dont install the
skill/snice man pages which means you will break any subsequent compiles
with the flags enabled. Man pages not to be installed should still be
distributed.

2) The git version into Makefile.am breaks under certain conditions.
The easy break for this is:
  touch aclocal.m4
  make

We need this script added plus some dist hook magic that got left out.
