Exporting to Makefile fails to build on Windows due to command line limit being exceeded

[srberard]

Description

Target
Any

Toolchain:
Any Makefile based export.

Expected behavior

mbed export -m <board> -i make_gcc_arm
make

Actual behavior

Error code:
make (e=87): The parameter is incorrect.

Per #6335, the issue is that the command line for the linking step exceeds the 32K limit on Windows. The proposed solution was to use a response file in place of passed everything on the command line. An example was presented here which I have confirmed works correctly.

@srberard This will have to come with a documentation update that include a link for windows users to download make >= 4.

@theotherjimmy Thanks for the update.

I'm not sure I understand your comment. Why is this a documentation update vs. a fix to the makefile or export process?

[theotherjimmy]

@srberard It's both. We should document a location for obtaining a compatible implementation of make in addition to taking the PR that updates the make exporter.

[srberard]

Awesome. Thanks for the clarification.

Closing since clarification PR has long since been merged.
