GCC 5.4 mips64el problems

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

I decided to try building evbmips-mips64el with GCC 5.4 (-V HAVE_GCC=53).
Starting with a completely empty OBJDIR/DESTDIR, etc., building eventually
failed with:

[...]

I understand others have been experimentally building evbmips (-mips64eb
at least) w/GCC 5.4.  Did you run into this and if so, what works around
it?

Thanks.
