g++ not finding libstdc++.so on Solaris

[Peter Kurpis]

When I do a vanilla build of gcc 2.95.2 on Solaris 7 (with or
without --with-gnu-as and --with-gun-ld), everything apparently 
works fine except...

...when I build with g++, the resulting executable can't find 
libstdc++.so.2.10.0 because the path (being /usr/local/lib) is 
not hardwired into the resulting executable.

I can work around this by setting LD_LIBRARY_PATH=/usr/local/lib 
(which is an undesirable kludge) or by setting 
CXXFLAGS += -Wl,-rpath /usr/local/lib in my master Makefile, but 
is there a more graceful way to set it up right?
