not produce proper exit code on ARM

[yichoi]

if run failed, it should generate proper exit code but always return 0

root@android:/data/tmp # ./yield.stage2-arm-linux-androideabi
rust: ~"\"1\""
rust: ~"\"4\""
rust: ~"\"2\""
rust: ~"\"3\""
rust: ~"\"5\""
rust: ~"\"6\""
leaked memory in rust main loop (5 objects)
assertion "false" failed: file "/home/yichoi/rust_latest/src/rt/memory_region.cpp", line 192, function "memory_region::~memory_region()"
[1] + Stopped (signal)     ./yield.stage2-arm-linux-androideabi
root@android:/data/tmp # echo $?
0
[1] + Segmentation fault   ./yield.stage2-arm-linux-androideabi

this leads wrong results when do make check series.

It might be related with #6231 but I am not sure.
