These should have been sent as plain text. That uses much less place
(your mail is 513KB hereover. Please count all the text lines in the
screen shots and think about it) and one could quote it.

That's a screenshot from the Makefile.linux. You have to use `diff -urN`
on the original and the changed file if you want to show changes between
them.

Irrelevant.

Both irrelevant.

More relevant would have been the cross-gcc's version if cross-gcc spits
out errors.

The "error: unrecognized option" stuff just means that we use options
for the gcc which are not supported by your cross-gcc - most probably
because it is (quite) old.
I wonder how old since he doesn't know "-Wextra".

So the most simple work-around is to just comment out the options which
your cross-gcc does not understand.
Or comment out "-Werror" so that the cross-gcc does not stop on
warnings. But that might make you ignore warnings which indicate real
problems ....
