796fb2ec8c Readd optimization last night. Problems earlier were partially due to the 
arguments names on one function being swapped (by a previous author).

Do not do any duplicate suppression when a source list is created.  Instead:
* OP_MADE protects against trying to make the source multiple times.
* A new OP_MARK flag is introduced to suppress duplicates while expanding
  the .ALLSRC variable and .USE targets.
This turns the O(n^2) insertion into O(n) in most cases.

This is tested with a `make build' and some special test cases.

edfd0106e2 Introduce an OP_MARK bit, and use it to suppress duplicates during .ALLSRC 
and .USE expansion.  Also, remove some more Lst_Member() checks that are now
redundant.

83f22c12ea Nuke an `optimization' that made source list creation O(n^2). This may cause 
more memory to be used with stupid Makefiles, but it saves a fair amount of
time (~13% just for libc) with sane ones.

cd8908a299 Rats! ${FOO:=bar} is a common usage of the SysV = modifier. 
To avoid that, we now do ::[+?!]*= but the SysV = modifier can
conflict with any new modifier.  At there are currently no Makefiles
in our tree that use ${FOO::=bar}

339f702f71 Implemented a set of assignment modifiers. These solve obscure 
problems such as using modifiers on .for loop iterators derived from
local variables (eg .TARGET).
Unless the variable already exists in a global context, these assignments are
local to the current context (this is usually what is wanted).

edfc5b4270 Expand variables in variable name passed to Var_Set and Var_Append. 
This allows ${FOO}.bar=fubar etc to work.
This does not impact any Makefiles in the current tree but allows

82abb388a6 Revert to the original behaviour wrt sysIncPath, ie if sysIncPath 
is an empty list, use DEFSYSPATH.
The current behaviour may have been useful when DEFSYSMK was an
absolute path (hasn't been the case since 1996), but right now
make -m /no/such/dir will fail to find sys.mk and die.

5fe132c5cb Added the :U :D :L :P :! and :@ modifiers as used by ODE make. 
These allow some very useful magic in the makefiles.
The comment in var.c describing their behaviour is mostly lifted
from ODE make, but the implementation of the modifiers themselves
is quite different (much simpler) due to divergence of our code base.

0828d668af Changes to make MAKEOBJDIRPREFIX useful. 
Firstly, we ignore getenv("PWD") if MAKEOBJDIRPREFIX is set so that we always
get the same value for .CURDIR regardless of how make was invoked.

Second, when executing a command we check if it is ${.MAKE} or ${.MAKE:T}
without a preceeding chdir, if so we insert a chdir(${.CURDIR}) so that
the Makefile will be found by the child make.  Note that this behaviour is
dissabled if MAKEOBJDIRPREFIX is not set or if NOCHECKMAKECHDIR is set.
See the comments in main.c for more detail.

With these two changes, one can successfully build usr/src using MAKEOBJDIRPREFIX
allowing the src to be mounted from a CD-ROM.
