libtool scribbles into pipelines

[John Reiser]

ltmain.sh (GNU libtool) 1.4 (1.920 2001/04/24 23:26:18)

By default, libtool messes up pipelines because it writes "diagnostic"
output onto stdout instead of stderr.

Change
-----ltmain.in:99
show="$echo"
-----becomes
show="$echo  1>&2"
-----

Also change
-----ltmain.in:148
  --debug)
    echo "$progname: enabling shell trace mode"
    set -x
-----becomes
  --debug)
    echo "$progname: enabling shell trace mode"  1>&2
    set -x
    PS4='+$LINENO '   # greatly helps auditing!
-----

and probably most other "bare" uses of 'echo'.
