Thanks for the heads up. I guess it was me who mentioned CFLAGS first in 
my example, even though the man page clearly disadvises against this.

For me, from the destination host, I am using the MACHINE[_ARCH] from 
uname -m/-p respectively, hoping, it has been set correctly by the 
installer :)  Unless there is something that speaks against this method.
Otherwise, especially with arm, I would be totally lost.

But an impressive list anyway.
