I am pleased to be able to say that BOOT_CFLAGS= -g -O3
works for revision 196574 (Sat 09 March 2013).

I'll use this as my new default build setting,
so when it stops working I'll be able to put in a bug report.

This is a long way from -g -O3 being the default
for all architectures, but it is a good step forward.

I think this bug is fixed.
