Subject: Install libraries in correct directories on multiarch systems.
X-Git-Url: http://biod.pnpi.spb.ru/gitweb/?a=commitdiff_plain;h=d5c5abd9aa19fe7f5be442defca548576cac4fc5;p=alexxy%2Fgromacs.git

Install libraries in correct directories on multiarch systems.

NB: this patch may change the default install dirs on some systems,
and will _not_ overwrite previous installations. Thus make sure to
link to the correct library versions of e.g. libgromacs.

Fixes #591 and #623.
