No one else on FC has reported these problems and I think this must be
local to your situation. Note that Makefile.common looks like this, with
lines 63 and 69 highlighted with ***:

ifndef LLVM_OBJ_ROOT
include $(LEVEL)/Makefile.config
else
include $(LLVM_OBJ_ROOT)/Makefile.config  ***
endif

#
# Include all of the build rules used for making LLVM
#
include $(LLVM_SRC_ROOT)/Makefile.rules ***

The only way for this to produce these messages is if LLVM_OBJ_ROOT and
LLVM_SRC_ROOT are set before including Makefile.common. None of the
makefiles in LLVM do this. Perhaps you have these set in your
environment? If so, unset them. Or, perhaps you are including
Makefile.common from your own directory in which the Makefile sets
LLVM_OBJ_ROOT and LLVM_SRC_ROOT (incorrectly).

What is cmlog.sh ?

does cmlog.sh set LLVM_OBJ_ROOT and LLVM_SRC_ROOT? It shouldn't do that.
The inclusion of Makefile.config will figure them out.
