[bug #60399] Incorrect dependencies with grouped targets

[Paul D. Smith]

Follow-up Comment #1, bug #60399 (project make):

I agree that this behavior does not seem right.

First, the output of --trace is misleading.  Using -d is slightly more
understandable.

I think that the way it's implemented is that a prerequisite of any element of
a group is considered to be a prerequisite of the entire group.  So by saying
that b depends on FORCE, that also implies that a depends on FORCE: they are
considered a group and can't really be managed separately.  It wasn't really
considered that the out-of-date computation of one element of the group might
make a different decision on whether to rebuild, if only that one element was
considered.

Oddly, it appears that .PHONY (and, probably other special targets like it)
apply to individual members of the group rather than the entire group like
regular prerequisites.

Details:

Make searches the default include directories for included files.
This new option -a tells make to skip the default include directories.
In my practice, /usr/include, /usr/gnu/include and /usr/local/include contain
header files and never contain makefiles.
Users cannot store their owns hand-written makefiles or generated dep files in
these directories, because these directories are owned by root.
The only effect of this lookup is to slow down make.
Not sure, if this lookup can be removed from make. Therefore, this new option
to avoid it.
