Okay .. thank you. So that should not be needed for a release version
bootstrap.

It's a developer option so it's not documented but in the configure script:
./configure --help
[...]
--with-build-config='NAME NAME2...'
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81926
--- Comment #25 from Dennis Clarke ---
So this seems to be related to some env var BUILD_CONFIG ?
Ehere is this "BUILD_CONFIG" documented?

OK, I can reproduce with BUILD_CONFIG set to empty:
Comparing stages 2 and 3
Bootstrap comparison failure!
gcc/go/parse.o differs

I think Rainer's patch as well as the addition of the env vars that
point to "gobjcopy" and "gobjdump" have sorted this out. I get a
clean three stage bootstrap now on an sparc-sun-solaris2.10 arch

Regarding "BUILD_CONFIG" I have about ten log files and they all say :
checking for default BUILD_CONFIG...
I have never set that var to anything.

This is excellent follow up and it looks like GNU binutils must be around
somewhere on the system for "Go" to build. Also, I always run "gmake -k check"

I don't mean to ask what may seem obvious but does it make sense to
add a not required "dummy .text" section? I mean to say, is there a
valid reason why gas would add in a blank ".text" where none is
