IA32_FEATURE_CONTROL does not need to be checked by BIOS, in fact these
bits are needed only by SENTER and SINIT ACM. ACM ENTERACCS does not
check these bits according to Intel SDM. Also noticed that the lock bit
of IA32_FEATURE_CONTROL cannot be cleared by issuing neither global
reset nor full reset on Sandybridge/Ivybridge platforms which results
in a reset loop. However, check the IA32_FEATURE_CONTROL SENTER bits in

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.
