V3 testsuite not honoring multilibs?

[Mark Mitchell]

As far as I can see, the V3 testsuite does not use multilib options when 
testing multilibbed versions of the library.

For example, the tests run in the hpux64 multilib directory do not seem 
to use -mlp64 on HP-UX 11.23.  They seem to cheerfully just run in 
32-bit mode.

The -mlp64 flag does appear in the CC, CPP, and CXXCPP in the 
automake-generated hpux64/libstdc++-v3/testsuite/Makefile.  However, 
-mlp64 does not appear in RUNTESTFLAGS.

How are the multilibs supposed to get the correct multilib options when 
running tests?
