help in gbuild

Hi gbuild Wizzards !

If it works, don't fix it... but it is a brain itch I'm scratching.

I'm looking to improve our new help build with a clever way to deliver
collateral (companion) file for packaging.

The current way is as simple as copying existing files to the target as
shown below (and thanks to Stephan Bergman for the invaluable contribution):

(in helcontent2/AllLangPackage_html_media_lang.mk)

------8<-----
$(foreach lang,$(filter-out en-US,$(gb_HELP_LANGS)),$(eval $(call
gb_AllLangPackage_add_files_for_lang,helpcontent2_html_media_lang,$(lang),$(LIBO_SHARE_HELP_FOLDER)$(if
$(HELP_ONLINE),/$(PRODUCTVERSION))/media, \
    files/scalc/$(lang)/imtrigon.ods \
    files/scalc/$(lang)/trigon.ods \
    files/scalc/$(lang)/pivot.ods \
    files/scalc/$(lang)/functions_ifs.ods \
)))
------8<-----

Which requires that the ods files to exist beforehand for each of the
~40 languages we build. However not every language has it's localized
ods file so to build successfully we need to copy the en-US file to
$(lang)/ folder,

The en-US file is located in files/scalc/<file>.ods .

IOW,
If localized file exist, then deliver localized file to localized package

else deliver en-US file to localized package.

Is there a trick to change the gbuild piece above for the purpose?

Thanks in advance!
