[Libreoffice] [PATCH] Work around a bash-ism in configure.in

Greetings,

Configure.in eventually gets parsed by /bin/sh, and on Free/Net/OpenBSD 
/bin/sh is not synonymous with bash.  Therefore, bash-isms in configure.in 
can be problematic.

This patch eliminates a "test: : bad number" diagnostic on FreeBSD. 
Contributed under LGPL3+/MPL.

Thanks,
Mike Eberdt
