Richard Purdie 903710ab5c clang/meta-ide-support/meta-extsdk-toolchain: Add missing MLPREFIX 
'cross' dependencies are hard, the code currently handles adding MLPREFIX
in these cases but may not in future depending upon implementation.

Add the correct value explictly.

SUMMARY = "LLVM based C/C++ compiler"
DESCRIPTION = "Clang is an LLVM based C/C++/Objective-C compiler, \
which aims to deliver amazingly fast compiles, \
extremely useful error and warning messages and \
to provide a platform for building great source \
level tools. The Clang Static Analyzer and \
clang-tidy are tools that automatically find bugs \
in your code, and are great examples of the sort \
of tools that can be built using the Clang frontend \
as a library to parse C/C++ code"
