Well this is not right:
/var/tmp/portage/sys-devel/gcc-14.0.0_pre20231217/work/build/32/./gcc/xgcc: not

32 should not be there ...

--- Comment #4 from Andrew Pinski  ---
Looks like multilib support in libgrust is just broken. I suspect it would be
worse on other targets where there are many more multilibs.

I just did:
```
mkdir objdir
cd objdir
../configure --enable-languages=rust
make -j24
```

And it work ...

for the pkg build (original report): no
for the quick test I did earlier: yes because I was rushing, oops

I am testing out using an absolute path for configure right now. Seeing if that
changes things ...
