Automake,cygwin: 'make clean' with libtool wrappers...

[Charles Wilson]

On cygwin, by the time you reach the 'clean-binPROGRAMS:' target, 
bin_PROGRAMS has been transmogrified to have .exe endings.  But, when 
building dynamically linked executables on cygwin, you end up with:

<workdir>/myprogram  << wrapper script
<workdir>/.libs/myprogram.exe

In any case, it takes more than just 'rm -f ${bin_PROGRAMS)' to 
completely clean up this mess.  So, the following patch to lib/am/progs.am.

When ?LIBTOOL?, loop thru bin_PROGRAMS, and hunt for and delete each of 
the following:

  myprogram.exe   << static linked .exe's go here (cygwin, DOS?)
  myprogram       << wrappers for dynamically linked .exe's (cygwin),
                     and statically linked unix executables
  .libs/myprogram.exe  << dynamically linked exe's (cygwin)
  .libs/myprogram      << dynamically linked unix executables
  _libs/myprogram.exe  << dynamically linked exe's (DOS?)
  _libs/myprogram      << ??? didn't want to leave anything out...

That covers all the possible "droppings" that libtool could create, on 
windows-ish platforms, dos-ish platforms (_libs) and unixoid ones.

(This patch also helps fix massive testsuite failures in the libtool 
package, when gets really confused by the random presence of old wrapper 
scripts -- when the current testbuild is static only ...)

        * lib/am/progs.am: make sure to clean up all the
        libtool droppings when doing 'make clean'
