This is wrong AFAIK. Your should not have such a link. If you have an
"asm" link here too, you shouldn't either. You must have two sets of
linux+asm includes. One in /usr/include, that matches the ones your libc
was build with. And one in /usr/src/linux/include (or whatever) with the
ones for your running kernel. The first ones should *not* be symlinks
pointing to the second ones. They must all be read directories.

I know that old systems do it that way but that's bad and it is known
that i2c and lm_sensors have difficulties building in these conditions.

Still...

isadump doesn't compile on non-i386 targets, and isn't useful here
either. Edit prog/dump/Module.mk and remove isadump from
PROGDUMPTARGETS, PROGDUMPSOURCES and PROGDUMPBININSTALL.

We should either fix isadump or remove it from the targets on non-i386
systems, but I don't know how to do that. MDS?

Thanks for reporting, let us know how it goes.
