[pacman-dev] [PATCH] Fix cross-compilation issues with git and libfetch

[Matthias Lanzinger]

This patch fixes 2 issues I encountered when cross-compiling pacman.
First is the test for libfetch which requires explicit linking to all
libraries libfetch depends on.

The other problem results from the AC_CHECK_PROGS test for git. This
test will stop configure with an error when cross-compiling.
The fix moves the call to AC_CHECK_PROG so that is only called of
--enable-git is actually set.
