Thanks a lot for the tips.

I think I'll go for the 2nd solution, with the least quotes and the
content of "define ... endef" the closest to the one of the
toolchainfile.cmake file (only $ needs to be escaped).

However I have no strong opinion about this, so if someone thinks to a
better solution, please speak up.
