What's the error? I don't think GCC requires a recent binutils, it should
build with reduced functionality when an old binutils is present.

Why can't you download a .gz or .bz2 file instead? Binutils provides
multiple formats.

This looks like some shell variable after < failed to get set and so
expands to nothing. Because that syntax isn't valid on Linux either.

Check if there's a newer GCC and/or binutils installed in the ports
collection, or in /opt/cfarm

Otherwise you could use the installed system GCC to build GCC 4.8.5, then
use that to build trunk. But it shouldn't be needed, using clang and the
system binutils should work.
