FWIW, the libc++ option is named:

  option(LIBCXX_ENABLE_SHARED "Build libc++ as a shared library." ON)

and the LLVM option is named (strangely without an LLVM_ prefix):

  option(BUILD_SHARED_LIBS
    "Build all libraries as shared libraries instead of static" OFF)

so it might be more consistent to leave the option with the proposed sense. We might even want to mirror libc++ more closely and name it LIBOMP_ENABLE_SHARED.

I don't, however, feel strongly about it either way. I would like to get this in, however; it is something we need.
