I should add that I had a similar problem only a couple of weeks ago
with a different piece of software. The .o files were of type "Mach-0".
The developer did his developing on a Mac, and the tarball contained the
.o files from his own builds. He didn't have a 'make clean' or 'make
distclean' in his Makefile, so I had to resort to

find . -name \*.o -exec rm \{\} \;

which fixed the problem.
