test for CXXLD

[Nicolas Bock]

Hi,

The C++ compiler I am using (charmc) needs an additional command line
argument during the linker stage (-language charm++). I am unsure how to
best add this argument. The generated makefiles use CXX for compilation and
CXXLD for linking, both of which are set to "charmc". How would I change
CXXLD to add a flag? Or is there a cleaner way to accomplish this?

Thanks already,

nick
