Excellent. Make moves in mysterious ways, its wonders to perform.

Stick a $(pwd) in there, as in

    make CC=$(pwd)/../1c/8cc

? That blows up for me because of the CFLAGS, but at least it seems
like a step towards doing what you want.

I'm not entirely sure that that the paths are the only environmental
pollutants in the result (in particular, I suspect the system time might
make its way in somehow, though I have very little evidence to support
this). There's a lot of confusing hype around `reproducible builds',
but the `Tips & help' section of
might be useful. Your script will be able to ignore things like Locales
or Time zones, of course, since the machine will be constant.
