The problem with clang on i386 has been fixed now. You need to update
devel/llvm, lang/clang and editors/libreoffice.

As for WITH_GCC, I think it's mostly there for testing purposes and
not really as a user option. The reason is that the gcc ports use
their own C++ libraries (instead of base system libraries) and that
means to be safe all C++ code should be built with it, not just
libreoffice.
