Work around -isystem strangeness in libreoffice build system

After libc++ 3.8.0 was imported in r300770 (see also bug 208158), Antoine found that editors/libreoffice failed with the following errors [1]:

This is because libreoffice's build system transforms some of the -I options passed via the port Makefile to -isystem, and one of those options is -I/usr/include, which screws up the include path order for C++ programs.  It turns out the -I/usr/include path is brought in via OPENSSL_CFLAGS, so set that to a single space to work around this.  (Note that OPENSSL_CFLAGS cannot be empty, otherwise the configure script will complain about not being able to find openssl.)
