The 'cross' directory

[Eli Zaretskii]

The file cross/README, though somewhat terse, seems to say that this
directory is for cross-building Emacs.  AFAIK the only target for
which Emacs can currently be cross-built is Android.  But the portion
of configure.ac that creates subdirectories in this directory and
copies (links) files there is conditioned by

  if test "$XCONFIGURE" != "android"; then

So this seems to run in any build but Android?

In any case, it sounds like creating those subdirectories and linking
files there is only needed in the Android build.  And if so, can we
please avoid doing this unnecessary stuff in other builds?

Thanks.
