GIT_DIR exported buring rpm build

[Jakub Bogusz]

Is $GIT_DIR exported intentionally when executing %prep, %build,
%install?

E.g. python pbr buildsystem tries to rebuild some files (AUTHORS,
ChangeLog) from git; when $GIT_DIR exists and points to package git
directory, these files are overwritten by authors and changelog from PLD
packaging instead of upstream software.
