Probably it's the network policy.

Thanks, but sorry, I've changed my mind..
For safety, I would like to keep the ping check, and I will give up
the automated "git clone" in the specific environment. I found that
I can build it by manual "git clone" and "make extensions".
Could you check the following patch again?

Subject: [PATCH] extensions/eppic.mk: move ping check to recipe script
Without this patch, in an environment where ping to github.com does
not work, "make clean" at the top-level crash directory always takes
about 10 seconds unnecessarily.
$ time make clean
