HOSTCFLAGS: Should not be set the same as CFLAGS since CFLAGS may be for a completely different platform. Use sane defaults like other configs/*/*/Make.defs.
ARCHCPUFLAGS: Depending on how the GNU compiler was built we may need -fno-stack-protector. Since we always want it we can just default to specifying it instead of depending on the compiler default.
LDFLAGS: If compiling for a 32 bit target from a 64 bit platform we need to tell the linker to generate a 32 bit elf file with -m elf_i386.
