[dpdk-dev] [PATCH v2] buildtools: output build failure reason to stderr

[Andrew Rybchenko]

If build fails because of failed experimental check and stdout is
redirected to /dev/null, it is absolutely unclear why build fails.

Fixes: a4bcd61de82d ("buildtools: add script to check experimental API exports")
