and those that are defined by the infrastructure (_BUILD_DEFS). This
allows the build-defs-message target to be moved to the end of
bsd.pkg.mk. Now it prints the correct result even in unprivileged
builds, which had been wrong due to the order in which the files have
been included. For example, ${UNPRIVILEGED_USER} was displayed as (not
defined) although its value was defined, which could be checked with
"bmake show-var".
Tested with one package that _does_ define BUILD_DEFS and with one that
doesn't. The behavior stays the same.
particular packages to compile correctly. bsd.hacks.mk auto-includes
the hacks.mk file in the current directory. An example hacks file:

.if !defined(FOO_HACKS_MK)
FOO_HACKS_MK= defined

.if !empty(MACHINE_ARCH:Marm*)
PKG_HACKS+= optimisation

The comment which heads each individual hack should timestamp when the
hack was added and describe the bug that requires the hack. By
separating out hacks to a separate file, we should be able to simplify
package Makefiles so that they are more readable.
