[PATCH] improve code for sysroot --mode=finish

[Paolo Bonzini]

Here are the improvements you suggested.  I'll send a patch for
sed_make_literal_regex soon.

Ok?

Paolo

* libltdl/config/ltmain.m4sh (func_mode_finish): Change sysroot_regex
and sysroot_cmd delimiter from pipe to slash.  Wrap the entire for
loop with "if $opt_dry_run...fi" and print an explanatory message
for the --dry-run case.
