To choose between "global" (default) and "tls" (new)
for -fstack-protector, -fstack-protector-all, and
-fstack-protector-strong (GCC 4.6+).
Note that this alone doesn't enable any -fstack-protector*
For NDK: The default "global" generates code backward
compatible with older bionic
For AOSP: build may add "-mstack-protector-guard=tls" to
build platform code with new bionic (*1)

After https://android-review.googlesource.com/#/c/45416 bionic provides
stack-protector random value per each thread at %gs:20. Therefore return
compiler back to %gs:20 code gen, same as for glibc.

* 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.
(stack_protect_test_<mode>): Likewise.
* gcc/defaults.h: Define macro TARGET_HAS_BIONIC to 0 - target
* does
not have Bionic by default
* config/linux.h: Redefine macro TARGET_HAS_BIONIC to
* (OPTION_BIONIC)
Macro OPTION_BIONIC is defined in this file and provides Bionic
accessibility status
2012-05-16 Igor Zamyatin <igor.zamyatin@intel.com>
* configure.ac: Stack protector enabling for Android targets.
* configure: Regenerate.
