Some new testresults - irix6.5 with -mabi=64

[Benjamin Kosnik]

Did you see this part of lib/libstdc++-v3.exp? It's copied directly from 
g++.exp, which I assumed worked.... 

# On IRIX 6, we have to set variables akin to LD_LIBRARY_PATH, but
# called LD_LIBRARYN32_PATH (for the N32 ABI) and LD_LIBRARY64_PATH
# (for the 64-bit ABI).  The right way to do this would be to modify
# unix.exp -- but that's not an option since it's part of DejaGNU
# proper, so we do it here, by trickery.  We really only need to do 
# this on IRIX, but it shouldn't hurt to do it anywhere else.
proc libstdc++-v3_set_ld_library_path { name element op } {
  setenv LD_LIBRARYN32_PATH [getenv LD_LIBRARY_PATH]
  setenv LD_LIBRARY64_PATH [getenv LD_LIBRARY_PATH]
}

trace variable env(LD_LIBRARY_PATH) w libstdc++-v3_set_ld_library_path
