  [Flang-RT] Fix GCC 15.1 Fortran Runtime libstdc++ Undefined Symbols (#157385)

Define the _GLIBCXX_THROW_OR_ABORT macro to not use its _EXC argument. _EXC may contain an expression constructing an std::exception object which is non-inline and therefore require a link dependency on the libstdc++ runtime. In -fno-exceptions builds it is typically optimized away when appearing in unreachable code, but is still present when compiling with -O0 when compiling with Clang.
