#3384 Regression tests failing, but green dots on snapshots page

[Philipp Klaus Krause]

Looking at the snapshots page, I see green dots, despite two tests failing for mcs51:

~~~~

In current trunk, these two tests are disabled via support/regression/MakeList, so to reproduce the issue that file needs to be changed.
