Add new build option KERNEL_USE, which compiles with -mkernel and gets propogated to CFLAGS. Use this to call panic() instead of abort() when enabled.

Add a VISIBILITY_HIDDEN option, which can be used to make all compiler-rt function definitions hidden/private extern.

libraries to generate.
 - Each library may be built with different flags and for different
   architectures, and there is support for building Darwin style fat archives.

 - Uses an ambituous amount of make programming, but should be hidden to
   users and developers.

Add 'SelectFunctionDir' function, to select appropriate function implementation based on a configuration and architecture.

 - Rest of makefiles will move to using the information after it has been computed, instead of during subdir traversal.

Also, add 'make info-functions' target, which prints information on all the functions available in compiler-rt.

Also, add 'make help-devel' for listing help on targets intended for compiler-rt developers or direct users.

Simplify subdirectory makefiles, and be more robust by checking that they define the appropriate variables.

Rename DebugMake variable to DEBUGMAKE for consistency (variables that are designed to be overridden), and use VERBOSE=1 instead of VERBOSE!="" for controlling verbosity.
