Compliment the existing GIT_TEST_INSTALLED variable added in [1] with
one that allows for testing a git built in a directory that's not
"../".
Instead of "test this installed git" ("GIT_TEST_INSTALLED"), this new
"GIT_TEST_BUILD_DIR" is a "test this built directory over
there". E.g. this will pass all tests:
git clone --depth=1 https://github.com/git/git.git git1
cp -R git1 git2
make -C git1
[apply this change to git2]
(cd git2 && GIT_TEST_BUILD_DIR="$PWD/../git1" make -C t prove)

installed git, 2009-03-16)
