I've fixed this now so that everything is in /usr/include/hcc.  The previous
build had all the headers symlinked into /usr/include because this is what some
apps, like hip, expect.  I've also updated the output of hcc-config --cxxflags
to add /usr/include/hcc as an include directory to support applications that
don't use the hcc prefix in their #include directives.

This is ok for a compiler.  It's possible to use the hcc-runtime without hcc, I
think hip may do this, so this is why I separated the headers and libraries
into separate packages.

hcc uses and depends on internal libraries, so this is OK according to
https://docs.fedoraproject.org/en-US/packaging-guidelines/#_rpath_for_internal_libraries 

> "hcc-config --cxxflags" still returns "-I/opt/rocm/include" but lacks

These include paths are fixed now.

I read that too, but upstream still ships this so it is an upstream issue
