The changes in af272aca591fe1dc0f1be64ae5bda147ea98a047 only works when
using gcc/g++ with -E or -save-temps, otherwise newlib's newlib.h gets
used even if -specs=nano.specs is specified. This is because the driver
only use cpp_options spec for the external cpp tool, not for the
integrated one.
This patch uses instead cpp_unique_options which is used in all cases:
it is used directly when the integrated preprocessor is used, and
indirectly by expansion of cpp_options otherwise.

Hi,
The changes in c028685518a261f6d0dab0d7ed15f9570ab9b3d0 to use
newlib-nano's include directory work for cc1 but not cc1plus. cc1plus
comes with its own cpp spec which does not have a name attached to it.
This patch uses the renaming trick on cpp_options instead of cpp, as
cpp_options is used both by cc1 and cc1plus.
