ARM: 8749/1: Kconfig: Add ARCH_HAS_FORTIFY_SOURCE
CONFIG_FORTIFY_SOURCE detects various overflows at compile-time.
(6974f0c4555e ("include/linux/string.h:
add the option of fortified string.h functions)
ARCH_HAS_FORTIFY_SOURCE means that the architecture can be built and
run with CONFIG_FORTIFY_SOURCE.
Since ARM can be built and run with that flag like other architectures,
select ARCH_HAS_FORTIFY_SOURCE as default.
