libgrust: 'AM_ENABLE_MULTILIB' only for target builds [PR113056]

..., but not for host builds, which don't need it, and it may cause the
build
to fail.

Use what appears to be the standard pattern for that (see
'libbacktrace/configure.ac', 'zlib/configure.ac').

PR rust/113056
libgrust/
* configure.ac: 'AM_ENABLE_MULTILIB' only for target builds.
* configure: Regenerate.

Notice that this is the *host* libgrust build -- unexpectedly multilibbed. 
Please test

"libgrust: 'AM_ENABLE_MULTILIB' only for target builds [PR113056]".

Reproduced, and I think I know what's happening.

failed for me as well, so out of source indeed fails as well

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

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

And it work ...

Looks like multilib support in libgrust is just broken. I suspect it would be
worse on other targets where there are many more multilibs.

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 ...
