Building net/ifdepd with clang and lld 13 results in a few warnings, and
a link error:

cc: error: linker command failed with exit code 1 (use -v to see invocation)
*** Error code 1
The warnings about misleading indentation are indicating an actual bug,
which can be fixed by adding a few braces. The link error is because
ifdepd uses an inline function without either a static or an extern
specifier. Fix this by adding a static specifier.
