bde 61e58ad58c Quick fix for high resolution kernel profiling on i386's. Use
-finstrument-functions instead of -mprofiler-epilogue.  The former
works essentially the same as the latter but has a higher overhead
(about 22 more bytes per function for passing unused args to the
profiling functions).

Removed all traces of the IDENT Makefile variable, which had been
reduced to just a place for holding profiling's contribution to CFLAGS
(the IDENT that gives the kernel identity was renamed to KERN_IDENT).

# Part of unified Makefile for building kenrels. This includes all
# the definitions that need to be included after all the % directives,
# except %RULES and things that act like they are part of %RULES
#
# Most make variables should not be defined in this file. Instead, they
# should be defined in the kern.pre.mk so that port makefiles can
# override or augment them.

# XXX why are only some phony targets marked phony?
