[hybrid] Bad change to INSTALL-file

[Henri Salo]

Change in this commit[1] is bad since normal Linux-machine does not have
gmake-binary. It usually is only installed in BSD-machines. One should change
that back and add note about using gmake in machines, which does not have GNU
make named as make. I wonder how ircd-hybrid developer doesn't know this
already, but there is other INSTALL-files as well, which should be
updated[2,3]. One could also print information about this if we can find gmake
from system when running configure.

Also there is broken SVN-link[4] in[5] as Michael might have already noticed.
We really should have www-page in SVN.
