This function cannot be easily and (more importantly) correctly ported
without cooperation from the libc stdio layer. We already document that
users should be prepared to have the function not available on some
platforms and that they should ideally switch their code to other
more portable and better interfaces.
Instead of making the build fail, and requiring porters to add
exceptions for something that most probably cannot be ported correctly
anyway, simply print a warning and let it build. This will not be a
regression because on those systems libbsd would have never been built
before.

test: Fix explicit_bzero() test on the Hurd
On the Hurd a small read(3) might end up (indirectly) copying the data
on the stack, which we will end up finding even when we have cleared
the buffer.
To avoid these side effects, we add a new function, that we force not
to be inlined, so that we can reuse the same stack space, that will
blank any possible stack side effects. This should be portable
regardless of stack growing up or down.

Switch md5 compatibility logic back to direct linking
When using the recent dlsym() based wrapper, we are not requiring any
symbol from libmd, as we resolve those dynamically at run-time. We were
ending up linking against libmd because in another part of the code we
require (depending on the architecture) the SHA512 functions for the
getentropy() local implementation. But that function might be provided
by the system libc on some systems, which means we end up not linking
against libmd at all.
To solve this we go back to the previous simpler solution of linking
directly, which had the main drawback of then making programs fail to
link when not specifying -lmd (on platforms that need it). And then
switch the .so link point from a symlink to a linker script, so that we
can inject the -lmd library as-needed. This is similar to what glibc is
doing.

build: Split libmd dependency due to MD5 functions from SHA requirements
To be able to rework the md5 deprecation logic, we need to detangle when
we depend on libmd due to requiring MD5 functions, which might be
otherwise provided by libc, or when we require SHA functions for the
internal getentropy() implementation.

nlist: Remove condition which is always true
The nlist() function is limited to handle ELF binaries of the same class
as size as the size_t of the architecture built.
In addition the SIZE_T_MAX macro is BSD specific, and was falling back
to the wrong constant on most 64-bit non-BSD systems.

build: Allow building with -flto on gcc-10 and newer
Global asm statements (like .symver directives) do not work reliably
in gcc with link time optimization. Use the symver attribute introduced
with gcc-10 to set symbol versions instead, if available.
[guillem@hadrons.org:
- Simplify by using __has_attribute fallback from <sys/cdefs.h>.
- Coding style changes. ]
