Hi Peter,
Adding CC_EXTRA_OPTS=-DNOSMP to make command (example: make
CC_EXTRA_OPTS=-DNOSMP) solves the problem, even don't need to modify def's,
unless the system can't recognize this fact.
But also need to deal with the following:
During a compilation you'll get something like:
/tmp/ccr4MEib.s:5860: Warning: swp{b} use is deprecated for this
architecture
The swp{b} instruction is deprecated in ARMv6 and above. Worse, it isn't
supported at all in ARMv7 and is fixed up in the illegal instruction trap
in the Linux kernel - at some runtime cost. Your compiler should absolutely
not be generating it. Since raspi is armb6 arch - this warning will be
silently ignored, but if you'll build on cubieboard (A10/A20) - it will be
a catastrophe.
Regarding to SMP to ARMv6 - there is no SMP support. The SMP is only
above ARM9.

Hi Konstantin,
I used the latest raspbian distribution downloaded from
www.raspberrypi.org and the commands:
make cfg
make
This produced the error output I reported.
Making the change to Makefile.defs fixed that problem for me.
Presumably you had to set some extra options when compiling? So the
question is, should I commit the change to Makefile.defs to make the
compile work without extra options required?
The only reason not to make the change would be if someone has, or
expects to have, an arm6 device with SMP support.
Regards,
Peter

A process of compilation is exactly the same, but need to add
CC_EXTRA_OPTS=-DNOSMP because SMP is not supported for arm atomic
operations.
You can add this remark in WIKI if you need.
