Well, I don't know if this should be needed but I was able to fix the
problem by adding the use of the 'sizeof-long-4' test to the
testlist. This test fails with 'cc +DD64' since that has an 8 byte long
and we then correctly used the ABI=64 setting. I am tempted to say we
should add 'any_64_testlist="sizeof-long-8" too just to be sure. I
don't know if that is considered a reasonable thing to do or not. I
don't see any targets checking both long-4 and long-8.

Thanks, this might be a good thing to improve the resilience! But I
still don't see what triggered the initial problem. I need to
understand that before I make any changes.
If you simply do a "SRCPATH/configure" with the unmodified sources, what
is output? Please do not pass any CC or CFLAGS settings as configure
arguments, and also make sure they are not set in your environment.
In general when reporting problem like this, we need configure output.
