[PATCH] Fix linking for not-so-clever linkers.

From: Johannes Schindelin <johannes.schindelin@gmx.de>
Date: Jul 10, 2006, 11:40 UTC
Message-ID: <Pine.LNX.4.63.0607101340080.29667@wbgn013.biozentrum.uni-wuerzburg.de>

On one of my systems, the linker is not intelligent enough to link with pager.o (in libgit.a) when only the variable pager_in_use is needed. The consequence is that the linker complains about an undefined variable. So, put the variable into environment.o, where it is linked always.
