[GRASS5] 5.3: hard links vs soft links

[Markus Neteler]

The recent change to soft links seems to cause problems
also in 5.3. I just received a mail from a user who
downloaded the auto-generated CVS-Linux-binaries from the GRASS site.

Obviously the links are not set correctly (example):

/usr/local/grass53/bin/g.gisenv-> /hardmnt/grass0/neteler/grass_cvs_53exp_pserver_latest/grass-build/dist.i686-pc-linux-gnu/etc/front.end

It seems more work is needed to make soft links possible (with shared
libs). I'll revert the change for now.
