[dpdk-dev] [PATCH 5/8] scripts: allow tuning build options per test target

[Thomas Monjalon <thomas.monjalon@6wind.com>]

The global variables are reloaded between each build to allow
having different config options based on DPDK_TARGET.

Some checks can now be removed from the script as they can
be done in the devel config file.
