[mono-android] Fast deploy with different target and minimum SDK values?

[Zach Bean]

Hello,

I've got a project with target and minimum SDK values that aren't the
same (13 and 7, respectively).  Unfortunately, I'm not having any luck
using either the shared runtime or fast deploy options when debugging.  

If I leave the shared runtime enabled and try to deploy to an API level
7 emulator, I get an error saying "the minimum android version is higher
than this device supports."

If I disable shared runtime but leave fast deploy turned on, I get a
runtime exception saying it couldn't find mscorlib.dll in the
"/home/jonp/Development/xamarin/mono/BUILD/armeabi/install/lib/mono/2.0/mscorlib.dll directory".

If I turn both options off, I can run the software without any issues.
I've only been working on the project for a week or so, and thus far
I've been able to live with it, but it seems to take 3-5 minutes to
deploy in "slow" mode.  Those minutes are starting to add up and feel a
little frustrating.

Is there anything I can do to make these options work?  Of course, I'm
happy to answer questions and try things if anyone has any suggestions,
or needs information I've left out.

Thanks!
