"""
If the build* function is passed the compiler argument, for example, 'llvm-gcc',
it is passed as a make variable to the make command. Otherwise, we check the
LLDB_CC environment variable; if it is defined, it is passed as a make variable
to the make command.
If neither the compiler keyword argument nor the LLDB_CC environment variable is
specified, no CC make variable is passed to the make command. The Makefile gets
to define the default CC being used.
Same idea holds for LLDB_ARCH environment variable, which maps to the ARCH make
variable.
