1When WORKDIR is included in some other git checkout, version.sh calls git rev-parse
2and it returns some description from that upper git checkout even when rfkill is
3being built from release tarball.
4
5When returned description doesn't match with expected v0.4, version.sh exits
6without creating version.c
7    # on git builds check that the version number above
8    # is correct...
9    [ "${descr%%-*}" = "v$VERSION" ] || exit 2
10
11and build fails a bit later:
12    | NOTE: make -j 32 -e MAKEFLAGS=
13    |  CC   rfkill.o
14    |  GEN  version.c
15    | make: *** [version.c] Error 2
16    | make: *** Waiting for unfinished jobs....
17    | ERROR: oe_runmake failed
18
19Don't try git rev-parse, if there isn't .git in ${S}.
