I was a bit confused at first, because when I looked at the code in
http://troglobit.com/project/pimd/, it was using a traditional
configure.ac and Makefile.am, which surely shouldn't require passing
CROSS and CC at build time, and which also doesn't have any
--embedded-libc option.

The reason is that 2.3.2, which was released in March 2016, predates
the introduction of autotools as the build system.

Therefore, I see two possibilities here:

 - You stick with 2.3.2. In this case, you should use generic-package
   and not autotools-package, because at 2.3.2, pimd is clearly not an
   autotools-package. It's not because it works by chance with the
   current autotools-package infrastructure that a future subtle change
   in the autotools-package infrastructure, which is valid for real
   autotools package, will break this non-autotools package.

 - You move to the latest Git commit, which really uses an autotools
   based build system.

Thanks!

Thomas
