[ECOS] EXEEXT settable via CDL?

[sandeep <shimple0 at yahoo dot com>]

to set the extension of test images, one can edit toplevel makefile of buildtree 
and set EXEEXT to desired extension.

many months back, i had made a minor addition in pkgconf/rules.mak
> export EXEEXT := $(EXEEXT)

could this be a trivial patch, if useful??

using which i could avoid the need to edit generated makefile. i just needed to
- either "export EXEEXT=.xyz" in execution environment
- or "EXEEXT=.xyz make tests"

then i had searched in documents/internet to find a CDL way for this, but 
couldn't locate. also i had tried some calculated guesses on cdl names for this 
but no success.

the advisor/PM for ecos team in my workplace finds even setting 'export 
EXEEXT=.xyz' in his .bash_profile as quite user-unfriendly. so he wanted a 
default. to satisfy that i made a modification

ifneq ($(EXEEXT),)
export EXEEXT := $(EXEEXT)
else
# default extension for the xxx user
export EXEEXT := .xyz
endif

this way, he can work (once in a while) with his defaults and regular ecos 
developer can work with xyz/arm/synth etc.. etc..

PM/Advisor wants to have EXEEXT to come automatically into buildtree makefiles 
via some CDL options. Has any other developer met this kind of requirements and 
found a solution?

Does CDL provide a way for this?

I checked out ecos docs (sections related to build tree generation and building 
process) yesterday again. may be i missed something.

help please, so that things can be made a user-friendly, and i can close a bug 
at workplace.

My hunch feeling is, if via some CDL thing, EXEEXT comes into build tree 
makefiles, then like REPOSITORY and other make variables, it will be ending up 
in all the makefiles in buildtree.

export REPOSITORY := /cygdrive/D/current/ecos/packages

and if user wants to build the tests with different extension, in same build 
tree, user will either have to edit all these makefiles or faster might be to 
generate a fresh build tree (that would also mean compiling the ecos libraries).
