The lldb_cmake GreenDragon bot is now failing, e.g.:


This looks related to Pavel's change:

> Default to using in-tree clang for building test executables
> Summary:
> Using the in-tree clang should be the default test configuration as that
> is the one compiler that we can be sure everyone has (better
> reproducibility of test results). Also, it should hopefully reduce the
> impact of pr35040.
> This also reduces the number of settings which control the compiler
> used. LLDB_TEST_C_COMPILER is used for C files and
> LLDB_TEST_CXX_COMPILER for C++ files. Both of the settings default to
> the in-tree clang.

The error is:

CMake Error at tools/lldb/CMakeLists.txt:78 (message):

  LLDB test compilers not specified.  Tests will not run

Does the bot need to be reconfigured for these changes?
