[Bug-tar] build failure on Android

[Bruno Haible]

Hi,

Building GNU tar (newest sources from git, with newest gnulib) on
Android 4.3 fails:

  CC       wordsplit.o
../../lib/wordsplit.c:29:18: error: glob.h: No such file or directory

The reason is that Android libc (Bionic) does not have the glob() facility.
See https://www.gnu.org/software/gnulib/manual/html_node/glob.html .

The fix is simple: use the replacement from gnulib. With this patch, the
compilation succeeds and most of the tests pass:
