It would appear that the 2.15 libgcc.a is missing the magic bytes 
"!<arch>\012" at the start of the file.  These bytes are defined as 
ARMAG in include/aout/ar.h and should be emitted by the function 
_bfd_write_archive_contents() in bfd/archive.c.  For some reason this is 
not happening.  Perhaps you could investigate further ?

Cheers
