Description of problem:
While compiling the latest version of ikvm (for FE), I've encountered a problem
with a missing symbol in the System dlls. I'm not sure if this is down to being
on version 1.1.17.

Version-Release number of selected component (if applicable):
1.1.17-3

How reproducible:
Always

Steps to Reproduce:
1. Download the latest ikvm and build
2.
3.
  
Actual results:
Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.48029
Executing(%build): /bin/sh -e /var/tmp/rpm-tmp.48671
