Jenkins build is still unstable: FreeBSD_HEAD #564

Mon Aug 29 17:52:50 UTC 2016

I guess the quickest way is boot that VM, cd to
/usr/tests/lib/atf/libatf-c++ and run `kyua test atf_c++_test`
However I am not sure this provides enough information because stuff
under /usr/tests/lib/atf/libatf-c++ are all binary files.

FWIW, I would like to know, should these -target, --sysroot and -B flages be
given when compiling a normal program in a normal time?  In this test
case, kyua just wanted to compile test.cpp which includes sstream, it's
not during buildworld/buildkernel time, so files under /usr/obj
should not be used.
