There are var-SECURITY_PIE_CFLAGS, var-lcl_maybe_fortify and var-SECURITY_STRINGFORMAT which are helpful for OVERRIDES. Also add var-SECURITY_STACK_PROTECTOR, and drop hardcoded `_remove' overrides. Such as `4ca946c security_flags: use -fstack-protector-strong', it s/-fstack-protector-all/-fstack-protector-strong/, only tweak var-SECURITY_STACK_PROTECTOR is sufficient. The fix does not have any side affect on SECURITY_CFLAGS of glibc/ glibc-initial/gcc-runtime, these three directly assigned with "". ... SECURITY_CFLAGS_pn-glibc = "" SECURITY_CFLAGS_pn-glibc-initial = "" SECURITY_CFLAGS_pn-gcc-runtime = "" ...

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
