The code below is from the grsecurity-2.9.1-3.2.42-201304082214.patch.
1. There seems to be a typo HOSTCLFAGS instead of HOSTCFLAGS.
2. The the flags in HOSTCFLAGS are, as far as I know, only used when compiling tools used when compiling the kernel. I.e. they are not used for compiling the actual kernel. The KBUILD_CFLAGS variable is used for compiling the actual kernel. Is that the intention with the patch?
