libreoffice 4.4 on netbsd-6/amd64 build failures

[Christoph Badura <bad%bsd.de@localhost>]

Having added GCC_REQD=4.6 to libreoffice4/Makefile the builds now die silently
in the apache_commons directories. E.g.:

[build PAT] apache_commons_logging

The actual failure place changes on every invokation of the
pkgsrc Makefile, but it is always the ant invocation.  Setting
MAKE_JOBS_SAFE=no doesn't seem to have an effect.

Does it build for anyone on -6?
