util/ifdtool/Makefile: Fix building as standalone tool

Commit f1e401c6cb (util/cbfstool/flashmap/fmap.c: fix fmaptool
endianness bugs on BE) makes use of endianness conversion macros
in cbfstool's FMAP code, which is also used by ifdtool. At least
on Linux, the <endian.h> header provides these helpers, but only
when `__USE_MISC` is defined, which is defined in the <ctypes.h>
header when `_DEFAULT_SOURCE` is defined. This was accounted for
in `Makefile.inc`, but not in `Makefile`. As a result, trying to
build ifdtool as a standalone tool (i.e. not as part of building
a coreboot image) results in build errors because the endianness
conversion macros are not defined.

Define `_DEFAULT_SOURCE` in `Makefile` to fix the build errors.
