Building LLVM 7.0.0 on Fedora 28 x64 fails when building OpenMP due to
incompatabilities with Cuda include files:

gcc version 8.1.1 20180712 (Red Hat 8.1.1-5) (GCC) 

Building using gcc 7.3.0 rather than the default gcc 8.1.1 allows the build to
succeed, but the install then fails:
make install

rpm -qa | grep python2-devel
python2-devel-2.7.15-2.fc28.x86_64

all builds carried out using:
# When building with gcc-7.3.0 only
CC=/usr/local/gcc/bin/gcc  ; export CC
CXX=/usr/local/gcc/bin/g++ ; export CXX
# common to all builds
cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=/usr/local/llvm-7.0.0 -D
CMAKE_BUILD_TYPE=Release ../llvm
cd build
make -j16
make install

So again lots of things not working by default on one of the main linux
distros.

In previous releases I had to build without lldb, so I removed that and tried
again with gcc-7.3.0. This then worked so lldb is once again unable to build on
linux... 

/usr/local/llvm-7.0.0/bin/clang -v
clang version 7.0.0 (tags/RELEASE_700/final)

Candidate multilib: .;@m64
Candidate multilib: 32;@m32
Selected multilib: .;@m64

Interestingly the "Found candidate GCC installation" is the system gcc 8
release, not the 7.3.0 release it was built with... Not sure if this will cause
issues long term.
