The XT testdata install rules expect the testdata dir to already exist in
the build tree, but it doesn't actually create it. Instead, it relies on
the build-testdata define happening to be executed before it (which runs
zic which creates the dir). When we run in parallel though, it's easy to
hit a failure:
$ cd timezone
$ rm -rf $objdir/timezone/testdata
$ make check -j
...
cp testdata/XT1 .../timezone/testdata/XT1
cp: cannot create regular file '.../timezone/testdata/XT1': No such file or directory
Makefile:116: recipe for target '.../timezone/testdata/XT1' failed
make: *** [.../timezone/testdata/XT1] Error 1
