39e4b788d6ca7d1e1ad045059ec7d088fde8a0db is the first bad commit

    ntdll: Use the standard Interlocked* functions.

    Signed-off-by: Alexandre Julliard <julliard at winehq.org>

there's a similar regression in dlls/mf (and probably elsewhere):
/usr/bin/ld: topology.o: in function `topology_generate_id':
/home/pi/wine-bisect/dlls/mf/topology.c:871: undefined reference to
`InterlockedCompareExchange64'                                                  
/usr/bin/ld: mf.dll.so: hidden symbol `InterlockedCompareExchange64' isn't
defined
/usr/bin/ld: final link failed: bad value

didn't bisect it yet, but I suspect commit
5d5b6a1f35c6fee51dcef60818028061f03ce0ce.

interestingly, my other armv7l machine (PrawnOS), doesn't show this, with same
gcc/ld versions (didn't compare flags closely though).
