Comment:
The problem is that GCC is generating BSD-format archives with filenames
of the form #1//20, but where the filename stored in the field is actually
null-terminated in such a way that is is less than 20 bytes long. However,
our current code assumes that the archive-supplied length is exactly the
length of the string when indexing backwards to determine the file
extension, which means that it fails to detect that the files in the
archives are actually object files!
Simple fix is just to call strlen once we have copied the string out of
the object file.
