Hi!
This patch broke bootstrap when Ada is enabled on pretty much all arches,
see https://gcc.gnu.org/PR123490 (verified by reverting the commit and
the build then succeeds). Ada used to create directories like
objdir/gcc/ada/rts and objdir/gcc/ada/rts_32 for
gcc -print-multi-lib
.;
32;@m32
compiler, but now it creates objdir/gcc/ada/rts_. and objdir/gcc/ada/rts_32.

hunk in config-ml.in. Why was this changed at all, or why haven't
you just set ml_top_subdir and kept ml_subdir empty? Can one blacklist
the primary multilib? In any case, even if you need it for some reason,
I think it has to special case x$ml_top_subdir = x. and keep ml_subdir
var empty in that case as before instead of using /.
