sanitizer_platform_limits_freebsd.cpp must include <md5.h> from the OS,
not include/md5.h in GCC source tree which is included by libbacktrace
support. Disable libbacktrace on sanitizer_platform_limits_freebsd.cpp
to avoid include/md5.h to restore bootstrap on FreeBSD.

Err, but that will just get complaints about disabled libbacktrace backtracking
(from within the sanitizer?)?

It disables libbacktrace backtracking only on one file,
sanitizer_platform_limits_freebsd.cpp,
which contains only data on FreeBSD. I highly doubt that libbacktrace
backtracking is
used in it.

include/md5.h is a header we have control over, can't we just add to it
something like:
#ifdef USE_SYSTEM_MD5
#include_next <md5.h>
#else
Current header content
#endif
and arrange for that macro to be -DUSE_SYSTEM_MD5 when building that
libsanitizer source file?

Gerald, can you try this suggestion? You can add "#define USE_SYSTEM_MD5"
in sanitizer_platform_limits_freebsd.cpp for testing.

Yes, the patch below restores bootstrap on x86_64-unkown-freebsd12.
Okay for now (or does anyone want to / can anyone help with Makefile
trickery to -Define USE_SYSTEM_MD5 there)?

include and libsanitizer should use 2 separate patches. The libsanitizer
patch should be in libsanitizer/LOCAL_PATCHES.

Okay, thanks.
This is the first part I committed on Friday, the second will
follow today.

include: Allow for our md5.h to defer to the system header
This came up in the context of libsanitizer, where platform-specific
support for FreeBSD relies on aspects provided by FreeBSD's own md5.h.
Address this by allowing GCC's md5.h to pull in the system header
instead, controlled by a new macro USE_SYSTEM_MD5.

Here is an alternative to the patch changing a file imported from
compiler-rt upstream, so that we don't need to cary a local patch for that
particular problem.
Bootstrapped/regtested on x86_64-linux and i686-linux (verified that
-DUSE_SYSTEM_MD5 is passed only when compiling
sanitizer_platform_limits_freebsd.cpp) and Gerald in the PR said
it passed bootstrap on FreeBSD as well.
Ok for trunk?
