I have a low prio suggestion for the port.  It seems that when valgrind-devel
is built on 11, it does not know about newer syscalls.  So when this instance
of valgrind is run on 12 or HEAD, it is uncapable of handling new libc.

Is it possible (without too much efforts) to make valgrind forward-compatible,
hopefully just by enabling HEAD syscalls on all builds, instead of limiting
it to the target equal to the build system ?
