* config/i386/i386.md (stack_protect_set): Disable the pattern
for Android since Android libc (bionic) does not provide random
value for stack protection guard at gs:0x14. Guard value
will be provided from external symbol (default implementation).
(stack_protect_set_<mode>): Likewise.
(stack_protect_test): Likewise.
