This is a proposed change to the multi-sim.exp baseboard to make it more
useful when testing installed cross compilers. I wanted to use the
contrib/test_installed script that comes with GCC to test an installed
cross compiler using a simulator but ran into two problems. The first
was that test_installed did not allow me to set a target different then
the host I was running on. I have submittted a patch to GCC to allow
me to do this (http://gcc.gnu.org/ml/gcc-patches/2014-03/msg00301.html).
The other issue is that when multi-sim was running the compiler to
find the dynamic linker and rpaths it was running the system GCC instead
of the GCC I wanted to test. My fix for that was to check the GCC_UNDER_TEST
in this baseboard. I am not sure if this is the right way to do this,
no other baseboard in dejagnu checks for GCC_UNDER_TEST but if there is
a way to set things up in the test_installed script so I don't have to
use GCC_UNDER_TEST I was not able to find it.
So is an acceptable patch or is there a better way to find the compiler
I want to use?

* baseboards/multi-sim.exp (dynamic_linker_flag): Check GCC_UNDER_TEST.
* baseboards/multi-sim.exp (rpath_flags): Ditto.
