Subject: [PATCH 2/2] Makefile: Exclude .h files from target rule
This ensures that src/_features.h is not added to compiler cmdline which
can confuse the compilers e.g. clang as it may not like .h as valid input
and complain
| clang-11: error: cannot specify -o when generating multiple output files
| make: *** [Makefile:50: netplan-dbus] Error 1
| make: *** Waiting for unfinished jobs....
Upstream-Status: Submitted [https://github.com/CanonicalLtd/netplan/pull/175]
