macOS don't support -Wl,--start-group/--end-group

[rhapsodyv]

Using Native platform in macOS fails to compile because the flags -Wl,--start-group/-Wl,--end-group aren't supported in macOS.
The native platform build script can't fix it because the core is adding this flags.

This changes fix that: macOS don't support -Wl,--start-group/-Wl,--end-group flags.

I don't have an issue with using native dev-platform on my macOS. We also have tests for this case. Coud you provide a simple project to reproduce this issue?

I tried this project and got this message:

Maybe we are using different gcc versions?

Confirmed that GCC 10 have the same problem with --start-group too

This change broke the fix for #3282. I've created #3674.

My original fix remove -Wl,--start-group/-Wl,--end-group only from Mac, where it isn't supported.
