mkelfimage: Make -fno-stack-protector effective
mkelfimage uses different flags to compile as freestanding binary it does not pour CFLAGS into them during configure as a result -fno-stack-protector was never used. Which failed to build with compilers configured to build with ssp by default. It worked with gcc since we do not configure our toolchain to default to ssp Fixes errors e.g. | objdir/linux-i386/convert_params.o: In function `convert_params': | linux-i386/convert_params.c:(.text+0x9f4): undefined reference to `__stack_chk_fail' | objdir/linux-i386/convert_params.o: In function `compute_checksum': | linux-i386/convert_params.c:(.text+0xa71): undefined reference to `__stack_chk_fail' | objdir/linux-i386/convert_params.o: In function `printf': | linux-i386/convert_params.c:(.text+0xcc7): undefined reference to `__stack_chk_fail' | make: *** [linux-i386/Makefile:24: objdir/linux-i386/convert] Error 1 (From OE-Core rev: f6ed82482838e34202721be8f40ca1cc340c325e) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
