Remove unneeded per-rule *INSTALL variables.

[Ralf Wildenhues]

For now, this is the last (proposed) patch of the series.  It cleans up
the per-rule *INSTALL variables, which are in most cases not needed any
more because the rules now ensure that the respective directories exist.

These names have never been documented.  However, some packages, notably
coreutils[1], have come to use them in their rules.  Dunno if we should
keep them.  Coreutils would be simple to fix, as would other packages,
I'm rather a bit worried to introduce such an incompatibility at all for
no other reason than saving a few lines of Makefile.

Also, I don't know if anybody has come to rely on the flexibility of
being able to override the install program on this special basis.

I haven't pushed this yet.  Comments appreciated.

Thanks,
Ralf

     also if some previously needed macro file has been removed.
