unix/Makefile: Allow users to specify the C++ standard used.

Mainly for user modules.

Actually, I'm not sure the whole HASCPP17 part should even be there: it's not needed for the MicroPython source itself (that just needs at least c++11 because the usercmodule example uses that). I'd be happy to remove it, but it's maybe too late for that now (as in: people relying on it)?

Assessment

S Sonnet · medium

Both items concern C++ integration in the Unix port Makefile for user modules. The PR (#8305) improves the build system's handling of C++ standards for user modules (refactoring HASCPP17 detection, defaulting to c++11), which is directly relevant infrastructure to what the query asks about. However, the PR does not answer the support question of how to link a C++ shared library — it only adjusts which C++ standard is used when compiling. The query remains open as a how-to question.

Suggested action

Close the issue as a support/question item — it is not a bug report or feature request. If the user needs guidance, point them to the usercmodule example in examples/usercmodule/cppexample/ and PR #8305 as context for C++ standard configuration. No further action needed on the PR.
