Building libreoffice on 8.3 x86-64, not

[John Levine]

I have an 8.3 x86-64 system, fully patched, all ports but one up to date.

When I try to build libreoffice, it fails in various sub-builds.  Most of
the sub-builds work when I retry them, except for tail_build which fails
repeatedly.

It's using clang for the build, but I don't see any option to use GCC.

Any suggestions?  I have 500 megabytes of build logs if anyone wants
to look at them.

R's,
John
