--- Comment #5 from rdapp at linux dot vnet.ibm.com ---
I quickly built trunk without bootstrap on power7 BE
("--enable-languages="c,c++,fortran" --disable-multilib --disable-bootstrap")
and still get no new fails.  Do I need other build parameters?  Meanwhile I got
access to a power8 LE machine and will check there.

r248678 definitely introduced fails but r248680 should actually get rid of
them.  I can't confirm for every one of these but [6/6] was made specifically
to address fails on power.  Are all of them still present after r248680?
