[patch] AC_OBJEXT/AC_EXEEXT

[Lars J. Aas]

This is a solution that works for me on Linux/gcc and with the MSVC
wrapper on Cygwin.  I've removed the `conftext$ac_exeext' part because
$ac_exeext defaults to "" and ls on Cygwin reports the virtual file
conftest when the file is named `conftest.exe'.  If there is a point
in including it, please add it between the `conftest.exe' case and the 
`conftest' case.

        * aclang.m4 (_AC_COMPILER_OBJEXT, _AC_COMPILER_EXEEXT_O):
        Make the order of arguments for ls count by splitting the ls
        command into a sequence of ls commands.
