Strange build error: After syncing: last change Update to 4.2.0-rc3

[KurtE]

@pillo79, @facchinm: Yesterday I synced up to the Arduino branch, and did the west update, etc. to get to bleeding edge.

I also then rebased my PR for touch support to this... #134

I then did the build_all, (copied into Arduino space) and I am now trying things out.

I am running into a strange build error some of the time:

Invalid FQBN: getting build properties for board arduino-git:ArduinoCore-zephyr:portentah7: invalid option 'mode'

Compilation error: Invalid FQBN: getting build properties for board arduino-git:ArduinoCore-zephyr:portentah7: invalid option 'mode'

AFAIK - my boards.txt/platform.txt and the like are in sync.

Investigating

Note: this was somewhat self induced (I think).

That is with previous stuff, I updated the boards.txt to enable linked versus ltext option, as for: Getting more memory
space and maybe a chance to find where a crash happened in the ltext area...

I see that the option was renamed in the new stuff for the C33: Dynamic and Static - not sure exactly what they
are, but guessing static is linked dynamic is ltext...

Note: but currently using unadulterated boards.txt, and had do reload boards, etc but that option as you can see in
the picture for Mode was still there.

I think I finally got rid of it.... I did reload again, Selected Giga, it would build, I then selected Portenta C33 and saw
the different menu, tried build, then selected Portenta H7 and now the mode menu is finally gone and it builds...

Will probably close this, but others like @mjs513 might run into it as well
