[PATCH] use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh

The attached patch causes the various arch specific install.sh scripts to
look for ${CROSS_COMPILE}installkernel rather than just installkernel (in
both /sbin/ and ~/bin/ where the script already did this).  This allows you
to have e.g.  arm-linux-installkernel as a handy way to install on your
cross target.  It also prevents the script picking up on the host
/sbin/installkernel which causes the script to fall through and do the
install itself (which is what I actually use myself, with $INSTALL_PATH
set).

I don't believe it causes back-compatibility problems since calling the
host installkernel was never likely to work or be what you wanted when
cross compiling anyway.  If $CROSS_COMPILE isn't set then nothing changes.

I only use ARM and i386 myself but I figured it couldn't hurt to do the
whole lot.  I've cc'd those who I hope are the arch maintainers for files
that I've touched.
