Nowadays, the dynamic linker requires a mounted /proc with
/proc/self/exe for some features (notably $ORIGIN handling).  So it's
not self-exec only that doesn't work if /proc isn't there.  I guess
the kernel must make sure that /proc is always there (unlikely), or we
need a different mechanism to get this data.
