[Openmp-commits] [llvm] [openmp] [OpenMP][Offload] - Ensure OPENMP_STANDALONE_BUILD is defined (PR #94801)

[via Openmp-commits]

https://github.com/estewart08 created https://github.com/llvm/llvm-project/pull/94801

Without a value set conditional checks like
if(NOT ${OPENMP_STANDALONE_BUILD})
will not be able to evaluate to true.
Fixes issue introduced from PR #93463, which did not allow the OMPT variable to be propogated up to offload during a runtimes build.
