Check whether $mono-prefix/lib/mono/4.0/mscorlib.dll exists.

$mono-prefix can be indirectly determined from

	typeof(object).Assembly.Location

Maybe with pkg-config:

libdir=`pkg-config --variable=libdir mono-2`
test -f "$libdir/4.0/mscorlib.dll" ...

'mono-2' will be supported by Mono 2.8.
Earlier versions are using 'mono'.

Under Windows, the Mono prefix is stored in the registry.
