From: Christian Göttsche <cgzones@xxxxxxxxxxxxxx>
If CFLAGS set by the user contains the warnings override
`-Wno-error=implicit-function-declaration` the availability check does
not work properly. Explicitly enable and treat this warnings as failure
by appending the appropriate flag.
Also include CPPFLAGS in the check.
