According to the C standard, accessing the NULL pointer (memory at
address zero) is undefined behaviour, and so GCC is allowed to optimize
it out. Of course, accessing this memory location is sometimes
necessary, so this optimization can be disabled using
-fno-delete-null-pointer-checks. This is already done in coreboot, but
adding it to xcompile will also disable it for all the payloads. For
example, coreinfo compiled with LTO libpayload crashes when this flag
isn't set, presumably because the compiler is optimizing something out
that it shouldn't.

Asserting reset in RO instead of in RW has no impact on security or
performance, but it does limit improvements to this process later.
This fix removes reset line control from RO and makes these variants
consistent with other hatch variants.
This fix reinforces the concept from commit fcd8c9e99e
(hatch: Fix FPMCU pwr/rst gpio handling).

Newest clang compilers warn about "misleading indentation", and because

In glibc feature control macros, _DEFAULT_SOURCE is the shorthand to
tell glibc to enable "all the default stuff", meaning POSIX, BSD and
System V interfaces. However, this macro is somewhat recent and older
glibc versions (e.g. 2.12) are still occasionally in use that don't
recognize it yet. For the benefits of users with these versions, let's
also enable the deprecated _BSD_SOURCE and _SVID_SOURCE macros which
essentially achieve the same thing. We must continue to define
_DEFAULT_SOURCE so that newer glibc versions don't throw a deprecation
warning.
This patch should make BSD-style byteswap macros like le32toh()
available on these older glibc versions.
