Hi Alan,
just for the records, this is how my cross-build fails:

...

the reason for this is overwriting GMPINC for the auto-build generation, because
many test scripts include <gmp.h> which fails now completely (it is not installed,
I have it in-tree). But as you can see the actual invocation of the Build-compiler
has still GMPINC set.
