Hint:  HOSTCFLAGS is applied to code that needs to run on the machine that's
doing the build, not the target code.  So for instance, if I'm
cross-compiling on
an x86_64 	for an ARM target (which I do quite a bit, building Lede router
images
for my wireless), HOSTCFLAGS is applied to any x86_64 utility code that gets
built.  I don't know what code is in klibc, but an example in the kernel
source
tree would be 'objtool' - that runs on the host system during the build,
not at runtime.

What directory did you do that in?  It looks like you're trying to install a
whole
new kernel image, not a new initramfs that has an updated klibc on it.
