$ gcc -save-temps -fstack-protector -fPIE hello.c -o hello
$ ./hello
$ Hello World!
$ gcc -save-temps -fstack-protector-all -fPIE helloall.c -o helloall
$ ./helloall
$ Segmentation fault
helloall.s segfaults, hello.s runs fine. if -fstack-protector isn't to
be supported on arm, it gcc should ignore the option like done on
mips/mipsel.
