Some more install changes:

- "make install" now depends on "make altinstall" for most of the
work, and the binary is always installed as python<version> first,
with a hard link to python made by "make bininstall".

- Create the machine dependent directory if it doesn't exist, and
attempt to run the regen script in it (unfortunately this will fail
unless you have h2py in your $PATH - help!)
