email-test-patchset: add support for Make options.

email-test-patchset: add support for Make options.

aiaiai-test-patchset has support for kernel make options which allows the
user to have more fine grained control over the compilation process. However,
the email form did not support passing these options to the test program. This
patch adds a configuration (per project) for specifying make options, so that
the user can have this fine grained control over the kernel build process.

Artem: amend commentaries a bit.
