The combination of INSTALL.Linux and INSTALL.userspace are very close
to the installation instructions for FreeBSD, so I think renaming it
makes sense - something like the diff below (as well as
s/INSTALL.Linux/INSTALL/ throughout the other INSTALL docs).
Also it turns out that FreeBSD's make doesn't like the Makefiles, so I
just changed it to be explicit about GNU make.
