[Mono-list] MCS build failure

[Nick Drochak]

 mcs --target exe @list -o ilasm.exe
| make[2]: *** [ilasm.exe] Error 255
| make[2]: Leaving directory `/home/Administrator/mcs/ilasm'
| make[1]: *** [linux] Error 1
| make[1]: Leaving directory `/home/Administrator/mcs'
| make: *** [all] Error 2

IMHO, makefile on cygwin should use csc to compile. We should use mcs only
in makefile.gnu.
