[4.0.0] "make check-g++" fails linking tests on powerpc-apple-darwin7.9.0

[Douglas Gregor <doug dot gregor at gmail dot com>]

Running "make check-g++" for GCC 4.0.0 fails any tests that need to  
link on powerpc-apple-darwin7.9.0, with error messages such as:

/usr/bin/ld: warning suggest use of -bind_at_load, as lazy binding may  
result in
 errors or different symbols being used
symbol _tanl used from dynamic library  
/Volumes/scratch/dgregor/gcc-concepts-con
fig/powerpc-apple-darwin7.9.0/./libstdc++-v3/src/.libs/ 
libstdc++.dylib(single mo
dule) not from earlier dynamic library  
/usr/lib/libSystem.B.dylib(ld64.o)

We've seen these before on powerpc-apple-darwin7.x.0 (x < 9), but they  
were always fixed by updating cctools to something > cctools-495. I'm  
using cctools-576. The same problem occurs with mainline GCC (4.1.0).

Does anyone know how this can be fixed?
