Tom Stellard 32b65345c5 Add support for detection of devtoolset-8 
Summary:
The current llvm/clang et al. project can be built with the latest developer toolset (devtoolset-8) on RHEL, which provides GCC 8.2.1.
However, the result compiler will not identify this toolset itself when compiling programs, which is of course not desirable.

After the patch - which simply adds the name of the developer toolset to the existing list - it gets identified and selected, as shown below:

[bamboo@bamboo llvm-project]$ clang -v
