This seems to be the case:
# strings DIR1/usr/lib/libfetch.a > tmp1
# strings DIR2/usr/lib/libfetch.a > tmp2
# diff tmp1 tmp2

I'm compiling ports, but I could delete the files afterwards. It would
be nice to be able to compile stuff in the images in the future, though.
I think I'll just leave the files there for the time being. It's a size
reduction of less than 1 MB.
