So you're cross-building on an amiga?

It's not too surprising that -m68060 is broken. The lesser-used
optimizations often get broken. Anyway, you are building the *target*
with -m68060, which won't work on a Mac. If you want to tweak, try
adding "-V HOST_CFLAGS=-m68020-60" to the build.sh command line.
