I only verified build on Core2 where I built
(I do not have anything older). Still had
build directory on 1Tb USB drive so:

1) bfdsymify gives

According to http://en.wikipedia.org/wiki/X86_instruction_listings
instruction CMOVE is added in Pentium Pro, so Pentium MMX
does not have it

So it seems that specifying host machine does not seem to be sufficient
any more (even it shoud be sufficient). I had:

build=i586-pc-msdosdjgpp
host=i586-pc-msdosdjgpp
target=i586-pc-msdosdjgpp

in generated Makefile in directory gcc for stage 3.

It seems that all 4.6.X versions have the same problem (I checked
disassembler output for 4.6.0). Currently I can only suggest to
try older version (for example some 4.5.X,
4.4.X, etc).  It would be nice to get
feedback about results.
