Okay, what's going on here...
While `emerge grub` I got "configure: error: unsupported CPU type"
Here's "/var/tmp/portage/sys-boot/grub-0.97-r10/work/grub-0.97/config.log" :
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by GRUB configure 0.97, which was
generated by GNU Autoconf 2.65. Invocation command line was
$ ./configure --prefix=/usr --build=x86-pc-linux-gnu
--host=x86-pc-linux-gnu --mandir=/usr/share/man
--infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc
--localstatedir=/var/lib --libdir=/lib --datadir=/usr/lib/grub
--exec-prefix=/ --disable-auto-linux-mem-opt --with-curses
