[syslinux] host cross-compile patch

[Don Hiatt]

I tend to use the same tool-chain across various hosts so I made this
very simple patch that allows you to pass the cross-compiler name to
make ( e.g. make CROSS_COMPILE=i686-nptl-linux-gnu-).

I'm not sure if patches should be attached or just pasted inline so I
did both this time. BTW, it's relative to syslinux 4 but the same
changes work with syslinux 3 although the patch won't apply cleanly.
