The version of LLVM that I have installed on my Mac 10.14.4 is:
$ where clang
/usr/bin/clang
$ clang --version
Apple LLVM version 10.0.1 (clang-1001.0.46.4)
Target: x86_64-apple-darwin18.5.0
Thread model: posix
InstalledDir:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
I don't know how that compares to upstream clang v7.x...?
More below.

A few notes on your configure line:

The MPI C++ bindings are no longer built by default, and you're not enabling
them (via --enable-mpi-cxx), so you don't need to specify CXX or CXXFLAGS here.

F77 is ignored these days; FC is the only one that matters.

Do you need all these CFLAGS? E.g., does clang not -I that directory by
default (I don't actually know if it is necessary or not)? What does
-DSTDC_HEADERS do?

I don't have that version of clang, but I installed gfortran 6.3.0 via homebrew
and configured with:
./configure --prefix=/Users/jsquyres/bogus CC=clang FC=gfortran
'CFLAGS=-fvisibility=default -mmacosx-version-min=10.10
-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include
-fPIC -pipe -DSTDC_HEADERS' 'FCFLAGS=-fPIC -pipe' --enable-static --with-pic
--disable-dlopen --enable-mpirun-prefix-by-default
And Open MPI v4.0.1 build ok for me...?
