core: Added support for the clang compiler
Support for clang, a C compiler from the LLVM suite has been added.
Install clang and run 'make cfg CC=clang && make' for building. GCC Inline
assembly is supported.
TODO: clean warning caused by clang (-Wunused-variable, etc)
(cherry picked from commit 452c543de61d413351a5ac0816adc137d150824b)
