    aclocal.m4: call cygpath on mingw32 only
    
    The only reason I noticed is warning these lines on linux:
    
    ```
    $ ./configure --target=sparc-unknown-linux-gnu
    ...
    ./configure: line 9708: cygpath: command not found
    ./configure: line 9708: ArCmd: command not found
    ```
    
    POSIX shell syntax requires no spaces in assignments.
    Fixed guarding condition while at it.
