Summary:                    HOSTCC not exported by top level Makefile causes
makefw compile to fail
Description: 
The Makefile does not explicitly export HOSTCC.  As this is not in the
initial environment, GNU Make does not export it by default.  As a result,
the make in the kernel directory, which does not independently include
makeopts, the file that actually includes the definition of HOSTCC,
substitutes a null string for HOSTCC resulting in a command not found when
compiling the, host platform, utiity makefw.

I tried .EXPORT_ALL_VARIABLES, but it causes a lot of warnings about
missing parameters to basename.

The unsubstituted "install"s turn out to be in the top level file and they
are just install, not $(INSTALL).  I don't think I've exercised
kernel/GNUmakefile in install mode, even though it does include
$(INSTALL).

Unfortunately, as this is pre-familiarisation work and I'm using my home
machine, I'm probably not going to be able to investigate this further
until the weekend.  It looks like I may have to carefully trawl the kernel
Makefile for unset variables and check the environment to see what make
puts there implicitly.

I also need to work out a safe way of testing the make install. 
Slacktrack might help.
