I tend to simply add:

LDADD+= -lstdc++ -lm

However, yes I think there is room for change - maybe a new mk file - for
things like the above, and eg for flex/yacc files to output c++ lexers (had
a go a while back as bin/7293). I also find I need to change

#define __IDSTRING(name,string)                                         \
        static const char name[] __attribute__((__unused__)) = string

to

#define __IDSTRING(name,string)                                         \
        static char name[] __attribute__((__unused__)) = string

which may well not be the right thing! so that ident strings remain in
c++ programs.

Cheers,
