PR-108142 Remove empty directories created in the build directory.

This patch removes empty directories created in the build directory.
Directories are only created if required and all modula-2 build output
is created under m2.  Add m2.stageprofile and m2.stagefeedback rules.

gcc/m2/ChangeLog:

        * PR m2/108142
	* Make-lang.in: Change build directory to m2.
        Change all rules to dynamically create subdirectories
        when required.
	(m2.stageprofile): New.
	(m2.stagefeedback): New.
	* Make-maintainer.in: Change build directory to m2.
        Change all rules to dynamically create subdirectories when
        required.
	* config-lang.in: Remove static creation of build directories.

Hi Gaius,

I’m finding it hard to figure out how the configuration is supposed to work for cross compilers (and more so for Canadian/native crosses).

Apologies if this is already answered in other review (but maybe some notes would help in that case).

questions in-line, thanks
Iain

What does “stage1” mean in the case of a cross-compiler or a —disable-bootstrap configure?

Hi Iain,

many thanks for the comments.  The patch only addresses the empty
directories issue.  I take your point about Canadian cross compiler
problems.  I think there is confusion in my use of stage1, stage2,
stage3 directory names which perhaps should be renamed cxxobj1, m2obj2,
m2obj3.  All objects in cxxobj1 are created by 'mc' and 'g++' and this
would occur if the compiler is built native or in any cross
configuration.

The m2obj2 objects would be built from modula-2 sources using cxxobj1
and would be a developer/maintainer enabled option principally used for
debugging.  Finally m2obj3 is also used by developers to allow the
compiler generations output to be compared (cxxobj1 vs m2obj2 vs
m2obj3).  

This could coexist with the standard stage1, stage2, stage3 of gcc.  The
gcc stage check would only check cxxobj1 having been rebuilt by the
relevant g++/gcc.

I propose to rework the patch (renaming the directories) and ensure that
Canadian cross works (currently it doesn't) - although it was tested for
classic cross (build == host != target).

regards,
Gaius

stage1 (or the proposed newly named cxxobj1) is created when the first
generation modula-2 compiler is built (using mc/g++).

allows g++ to pick up the mc translated definition modules in the build
directory gcc/m2/gm2-gcc/G*.h.  Maybe I've misunderstood the question?
There is some redundancy when this macro is used within some rules (I'll
reduce the paths), thanks for spotting it!
