 I removed that `configure` option, but `configure` still seems to be in
 the same mood:

 {{{
 checking for isl 0.15 or later... yes
 The following languages will be built: c,c++,fortran,lto,objc,obj-c++
 *** This configuration is not supported in the following subdirectories:
      zlib target-libcilkrts target-libsanitizer target-libvtv target-
 libmpx target-libgo gnattools gotools target-libada target-libhsail-rt
 target-libffi target-liboffloadmic
     (Any other directories should still work fine.)
 checking for default BUILD_CONFIG... bootstrap-debug
 checking for --enable-vtable-verify... no
 }}}
