Well, it got further but I still have about 4000 more failures in the
installed test run than the in build tree version.  I see this failure
more than once:

Executing on host: arm-elf-gcc
/usr3/ftp_archive/gnu/gcc/ss/b-3.2.1/gcc-3.2.1/gcc/testsuite/gcc.c-torture/execute/20000112-1.c
testglue.o  -w  -O2  -DSTACK_SIZE=16384       -Wl,-wrap,exit
-Wl,-wrap,main -Wl,-wrap,abort -lm   -o
/usr3/ftp_archive/gnu/gcc/ss/b-3.2.1/r-arm-elf/20000112-1.x2    (timeout
= 800)
pid is 13355 -13355
output is
PASS: gcc.c-torture/execute/20000112-1.c compilation,  -O2
Simulator -run missing.
FAIL: gcc.c-torture/execute/20000112-1.c execution,  -O2

Which I take to mean that it can't figure out the simulator.

The next place the script uses the wrong gcc is during linkage.exp.

output is
cc -c 
/usr3/ftp_archive/gnu/gcc/ss/b-3.2.1/gcc-3.2.1/gcc/testsuite/gcc.misc-tests/linkage-y.c
>&/dev/null
doing compile

I notice another difference is that when run in tree, it skips 
the unsupported tests and doesn't for the installed run:

Executing on host: arm-elf-gcc
/usr3/ftp_archive/gnu/gcc/ss/b-3.2.1/gcc-3.2.1/gcc/testsuite/gcc.dg/20020122-2.c  
-O2 -fprefetch-loop-arrays -march=athlon -DSTACK_SIZE=16384 -S    -o
20020122-2.s    (timeout = 800)
pid is 26700 -26700
cc1: bad value (athlon) for -march= switch^M
cc1: warning: -fprefetch-loop-arrays not supported for this target (try
-march switches)^M

I see about 200 failure just trying to compile code that requires a 
particular -march switch or has inline assembly.  It looks like there
are a handful of other switches that aren't set.  The site.exp is:

set tmpdir "/usr3/ftp_archive/gnu/gcc/ss/b-3.2.1/r-arm-elf"
set srcdir
"/usr3/ftp_archive/gnu/gcc/ss/b-3.2.1/gcc-3.2.1/gcc/testsuite"
set GCC_UNDER_TEST "arm-elf-gcc"
set GXX_UNDER_TEST "no"
set G77_UNDER_TEST "no"

Is there more that has to be set that test_installed is not setting?

Thanks.
