For some reason we're defaulting to true. If I set the value to false, the tests pass.

runtime/eng/testing/tests.mobile.targets

Line 20 in 24544e0

<UseSystemResourceKeys Condition="'$(UseSystemResourceKeys)' == ''">true</UseSystemResourceKeys>

[mdh1418]

It seems like that is defaulted to true to help reduce the assembly size by trimming. I wonder if theres something specifically being trimmed out to cause it to fail.
