When CROSS_BUILD_TOOLS is set, set HOSTCFLAGS to CFLAGS otherwise CC
will be used with HOSTCFLAGS which seems wrong

This eats - among other things - -O2, normally set in /Makefile. And that breaks
CROSS_BUILD_TOOLS=y with CONFIG_FIT but without CONFIG_FIT_SIGNATURE because "if
(!IMAGE_ENABLE_SIGN)" is no longer optimized. I tend to believe this should
simply be reverted (which is what I'm doing locally in order to fix my builds).
I don't think this patch should be reverted, I sent it to fix a
cross-compilation build issue with host-openssl.
Indeed, without this patch, with CROSS_BUILD_TOOLS=y, tools/Makefile
sets HOSTCC=$(CC) but it forgets
to override HOSTCFLAGS, though, so the tools are built with target
compiler but host CFLAGS.
This raises a build failure if host-openssl is built before uboot-tools because
uboot-tools links with openssl headers from host which depends on pthread.h

So what is your suggestion to fix the O2-regression best?
