build: Avoid git warning when building from tarball.

The "git describe" command which is removed by this commit caused the
following warning when running "make" on a tree without .git directory
(extracted tarball or gitweb snapshot):

fatal: Not a git repository (or any of the parent directories): .git

This commit avoids the warning. Of course "make tarball" still fails
in this case, but this is expected.
