This breaks cross-compilation.
HOSTCFLAGS is for compiling the xconfig program and stuff like that. Suppose it includes '-m486'.
Now you want to cross-compile a kernel for SPARC, so you feed '-m486' to your SPARC cross-compiler --> BANG!
HOSTCFLAGS should only be used for it's original purpose, please use the appropriate flags for what you want to do...
