Binary libtest.exe is created from .libs/lt-libtest.c.
Please see comments in c-file - binary try to run "/bin/sh libtest".
On build system this is useless:
- binfmt_misc is setup to use wine to run PE executable:
 Command strace will show whats happen.
 On my build system its fail since:
 a) /bin/sh don't exists and
 b) I will not install born shell(PE executable) only to run the test 
(see bellow).
- on host system : first you should copy whole build three and second 
/bin/sh should exist as native executable on current drive.

I found this executable useless if we do cross-compilation but I could 
live with this.

This is born shell wrapper script for .libs/libtest.exe.

If you like to test something (command "make check") on build system you 
should run this script(!)
(note without .exe suffix) from Makefile[.in|.am] to do the tests.

Yes .libs/libtest.exe is real executable  and it is installed by command 
"make install".

I hope explanation above help.
