Hi Josh,

Shame on me... Last minute fix. I had tested this first by forcing
HOSTCC="gcc <CFLAGS> <LDFLAGS>" but I found it rather dirty. As it turns
out, my patch is not better.

Indeed, I also missed this (see above).

It looks like objtool does not use HOSTCFLAGS nor HOSTLDFLAGS (defined
in top Makefile). Do you see a reason why? Maybe it would be a good idea
to share these flags (adding some specific ones for objtool, if needed).

What do you think?
