When attempting to build various different solutions, xbuild throws a wobbler
on some proj files complaining that mscorlib has already been imported.
The workaround NoStdLib=true fixes this however it requires 2 builds, and
breaks other projects too if they are not built first.
Apparently the msbuild behaviour changed recently and XBuild hasn't been
updated as such.

Reproducible: Always

Steps to Reproduce:
1. Grab the included solution
2. Build the sln without any params at all.
3. Observe the mscorlib failure
Actual Results:  
: error CS1703: An assembly with the same identity `mscorlib, Version=4.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089' has already been imported.
Consider removing one of the references

Expected Results:  
Build Succeeded :D

The system its being built on, is 64bit gentoo, mono from the git built about 1
hour ago 08/06/2011 @ 12:00 GMT -- Master branch.
I also have other solutions if needed that fail.
