clang: Keep -qrtems and -B for compilers without -specs support

This is needed for building rtems correctly with Clang.

Note that this change does not mean rtems can build correctly with
mainline clang. However the change allows building rtems with a
Clang toolchain that has a rtems frontend similar that of GCC's
builtin rtems specs.
