It's
real 22m50,526s
user 1m37,024s
sys 4m25,220s
with
ARCHINCLUDES := ${shell $(INCDIR) -s "$(CC)" $(TOPDIR)$(DELIM)include}
ARCHXXINCLUDES := ${shell $(INCDIR) -s "$(CC)" $(TOPDIR)$(DELIM)include}
ARCHXXINCLUDES += ${shell $(INCDIR) -s "$(CC)"
$(TOPDIR)$(DELIM)include$(DELIM)cxx}
in nuttx/Make.defs.
So it's faster (23min < 36min) but still far away from 4-5min it used to be.

I must admit I thought about that idea also, but I wasn't sure about the
portability issue.
You could also think about a autogenerated Make.defs during configure with then
hard coded include paths which should be the fastest possibility.
Since Make.defs is already copied, perhaps it could also be modified on the fly.
