Yes, I'd noticed. I haven't looked properly into any of the failures
yet. The i586-aout fail is just not meeting the zero size section
test. That may not matter much. The others all show deficiencies in
real-world use of "objcopy --extract-symbol". We didn't see them
before due to not running any test of the option on anything but ELF
targets, and the old extract-symbol test didn't fail on MIPS due to
removing .reginfo. When it is present we get a zero size .reginfo
which results in a warning from nm (well, bfd really) "don't know how
to handle processor specific section `.reginfo' [0x70000006]".
So objcopy hasn't gotten worse, we're just sweeping less under the
rug.
