using those flags makes most run.  the linker segfaults when working on
helloaout.c, so that can't be good:

$ cris-elf-gcc ../../sim/testsuite/sim/cris/c/helloaout.c \
	-O2 -L/usr/local/src/gnu/sourceware/build/build-cris/ld -sim3 \
	-Wl,-mcrisaout -sim -Ttext=0 -lm -o helloaout.c.x -Bld
collect2: ld terminated with signal 11 [Segmentation fault], core dumped

$ gdb ld/ld core

Do you need "set solib-search-path" or "set sysroot"?
Core was generated by `ld/ld -mcriself --gc-sections -o helloaout.c.x /usr/lib/gcc/cris-elf/4.5.3/../.'.

no other target needs this.  i did some work about two years ago specifically
to avoid having to mess with dejagnu just to run `make check-sim`.

looks like the difference are just compiler flags ?  you can specify those on a
test-specific basis using the "cc:" field:
$ head -5 testsuite/sim/argc.c 
/* Basic argc/argv tests.
# mach: bfin
# cc: -msim
# progopts: a bb ccc dddd
*/
$ head -5 testsuite/sim/mdma-32bit-1d.c 
/* Basic MDMA device tests.
# mach: bfin
# cc: -mcpu=bf537 -nostdlib -lc
# sim: --env operating --model bf537
*/
