For me, r300886 didn't build at all, when I tried:

It always errors out at the very first file built for the libraries

This is because r300886 filters out the -isystem options that point to
${WORLDTMP}/usr/include. When I build using r300885, it errors out
while building the atf-c++ libraries:

It appears that there is a conflict between how sys/cdefs.h defines
_Atomic() and how the libc++ headers define it. It looks like the
definition in the libc++ headers is more suitable for gcc, so maybe we
should disable our custom definition in sys/defs.h when an external gcc
is used? Or at least, disable it when compiling for C++.
