Hello Anil,

Apparently, this package does not like to be configured and compiled
on one arch and then tested on another. And frankly, this is somewhat
of an exotic case, so I am not sure how representative your test
results are going to be.

I think there are two ways to address this:
- create symlinks with aarch64-linux-gnu- prefix linking to gcc, ld,
as etc on the model as required;
- do the build on the model using distcc, this way the actual
compilation work will be performed on your build machine but the
source and build trees would live inside the model (perhaps someone
else could confirm whether distcc needs elaborate support in the
project usually, but I don't think this is the case)

Regards,
Ard.
