[PATCH v2] Makefile: avoid breaking compilation database generation with DEVELOPER

3821c38068 (Makefile: add support for generating JSON compilation
database, 2020-09-03), adds a feature to be used with clang to generate
a compilation database by copying most of what was done before with the
header dependency, but by doing so includes on its availability check
the CFLAGS which became specially problematic once DEVELOPER=1 implied
-pedantic as pointed out by Ævar[1].

Remove the unnecessary flags in the availability test, so it will work
regardless of which other warnings are enabled or if the compiler has
been told to error on them.
