Makefile: switch to use CPPFLAGS -D_DEFAULT_SOURCE

This fixes a warning on Linux glibc:

/usr/include/features.h:187:3: warning: #warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" [-Wcpp]
  187 | # warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"
      |   ^~~~~~~

Tested on Void GNU/Linux glibc with gcc. Tested on various other platforms for
regressions too namely: OpenBSD, NetBSD, FreeBSD, Void GNU/Linux musl.
