  Log Message:
  [Driver] Do not generate error about unsupported target specific options when there is no compiler jobs

The upstream commit: https://reviews.llvm.org/D151590
added a new flag to mark target specific compiler options.

The side effect of it was that in cases when -### or -v is used without any
input file, clang started emitting an error.
It happened like that becasue there is no compilation actions created
which could consume/verify these target specific options.

This patch changes that error to a warning about unused option in situations
when there is no actions and still generates error when there are actions.

Fix for https://github.com/llvm/llvm-project/issues/64958

Differential Revision: https://reviews.llvm.org/D159361
