[Patch] Insufficient quoting in cygwin support code

[Paul Berrevoets]

Building libtool (cvs) on cygwin generates the following error in
libltdl:

dlltool: Syntax error in def file .libs/libltdl-0.dll-def:1

The problem lies in the definition of 'archive_expsym_cmds' in
libtool.m4. The variables '$#', '$2' and '$3' are being expanded by m4
into '0', '' and '' respectively. '[$]#', '[$]2' and '[$]3' should be
used instead. The patch is attached.

        * libtool.m4: Quote the $ in $#, $2 and $3 in variable
        'archive_expsym_cmds' for cygwin.
