mkelfimage: Make -fno-stack-protector effective

Browse Source 
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
