[Buildroot] [PATCH 8/9] RFC: Remove HOSTCFLAGS from kernel compile

[Grant Likely]

From: Grant Likely <grant.likely at secretlab.ca>

Setting HOSTCFLAGS when calling make for the kernel compile messes up
the tools that the kernel builds for itself.  Specifically, the
building of the device tree compiler (dtc) in arch/powerpc adds some
required flags to HOSTCFLAGS.  However, if HOSTCFLAGS= is specified
when calling make, then the local flags are never added and the kernel
compile fails.

This patch removes the HOSTCFLAGS= from $(LINUX26_MAKE_FLAGS).  I've
marked this patch as an RFC because I don't know what is really required
here.  Removing it works for me (of course), but it may break other users.
I just don't know if there is a better way to set HOSTCFLAGS so that it
doesn't override the settings that the kernel uses itself.
