Subject: Re: converting gcc from glibc to musl
i recompiled binutils with the musl wrapper, im assuming musl libs isnt the
issue since it doesnt make sense that it would search for itself but im
still not sure how to resolve the pointing issue. recompiling binutils with
the musl wrapper didnt resolve the issue obviously but would i need to set
an include or lib path for it or specify newlib like with gcc?
