That's bizarre.  I'm using all the script's defaults, so GCC 6 and
whatever the binutils default is.  The host platform is x86_64-linux,
Debian unstable - that _could_ make a difference but it seems like it
shouldn't.  The error message smells like a binutils bug...

I do also see the ia64 execstack failure, but not the SH failures
(since I'm using gcc6).
