Bootstrap failure on sparc-unknown-netbsdelf1.5W

[Aaron Lehmann <aaronl at vitelus dot com>]

I built gcc 3.2 with --enable-languages=c,c++ for this target
(natively) and it seemed to work fine. I decided to do a complete
bootstrap so that I could report the results. I did not make clean
between the "make" and later "make bootstrap". This bootstrap failed.

I ran make clean and then reran make bootstrap. The results were no
different:

There goes the second 15 hours of compiling :(

Binutils is version 2.9.1.

Is netbsd one of the targets where object files can not be reliably
compared, or is something wrong?
