The follows the pattern used in C++ and D drivers to pass -static-libstdc++
onto the target driver to allow spec substitution of static libraries.
NOTE: The general handling of Bstatic/dynamic and the possible use of static
libgm2 libraries is unimplemented in this driver so far. It seems likely
that the driver construction could be greatly simplified if the modula-2
runtimes were combined into fewer (hopefully, one) libraries.

gcc/m2/ChangeLog:
* gm2spec.cc (lang_specific_driver): Pass -static-libstdc++ on to
the target driver if the linker does not support Bstatic/dynamic.
