What's happening here is that the linker (ld.gold) is linking
together two object files, let's call them "a.o" and "b.o".
The linker detects that one of the objects (let's say "a.o") has
a marker indicating that it was compiled with the "-fsplit-stack"
option. The second object file "b.o" has no such marker (e.g. it
apparently wasn't compiled with -fsplit-stack).
In addition, the linker sees (from object file relocations) that
a function (let's call it AFunc) in a.o is making a call to BFunc
in b.o. In such instances the gold linker has a feature that will
perform a fixup/rewrite on the calling function to make sure that
when the call takes place, the stack is large enough (so that
-split-stack will have the right effect).
To apply this fixup, the linker is looking for a specific prolog
instruction sequence-- when it doesn't find that sequence, it
issues the error.
In the previous LLVM bug I cited, the problem was with the C
compiler -- it was marking the object as split-stack, but not
consistently emitting the prolog sequence that the linker looks for.
Your compiler is an up-to-date version of GCC, however, so it's
hard for me to believe that the compiler is at fault.
[This is a lot of technical detail, sorry about that].
Do you think you could rerun the compile by hand and send me some
of the output (e.g. regenerate the file "CheckSymbolExists.c" as
it appeared in the cmake output log?
Thanks, Than

Sorry for the delay in responding, this is a
very busy time right now for our team (release
freeze is happening at the end of this week).
Just in general, the gollvm build procedure uses
"cmake", and as part of this process cmake is
running various tests to make sure that the C
compiler you're using works properly, and to
detect whether the system you are building on
has the right header files, libraries, etc.
Of particular concern is the cmake check for
"mmap"-- the mmap() routine is definitely
available on Ubuntu, so it's puzzling that cmake
thinks it isn't available.
One thing you might do: after the build fails,
try looking at the debris in the CMakeFiles dir:
$ ls CMakeFiles
3.13.4 cmake.check_cache feature_tests.bin src.c
3.15.4 CMakeError.log feature_tests.c
TargetDirectories.txt
CheckIncludeFiles CMakeOutput.log
feature_tests.cxx test.o
CheckTypeSize CMakeTmp simple.cc
In that dir, look at "CMakeOutput.log" for the
place where this test is run:
Look for a section that looks like this:

the following output:
