Subject: [PATCH] cmake: allow build without c++

By default cmake also searches for a c++ compiler:
https://cmake.org/cmake/help/v3.7/command/project.html
"By default C and CXX are enabled if no language options are given."

This patch restricts the compiler to C to fix a build error detected
by the buildroot autobuilders:
http://autobuild.buildroot.net/results/c04/c04ff29b83c020573add597c355c57a6d9c9761d/build-end.log

Patch sent upstream: https://github.com/hsleisink/hiawatha/pull/30
