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.
Signed-off-by: Iain Sandoe <iain@sandoe.co.uk>
gcc/m2/ChangeLog:
* gm2spec.cc (lang_specific_driver): Pass -static-libstdc++ on to
the target driver if the linker does not support Bstatic/dynamic.

Oops pressed ‘send' too soon - this is part of the series for Darwin:
There are several modula-2 issues on Darwin, some blocking bootstrap on
one or more system versions.
This has been tested on powerpc/i688-darwin9 .. x86_64-darwin10,17,21 and
the prototype aarch64-darwin branch on darwin21.
OK for trunk?
thanks
Iain
