"emerge-chroot -1 gcc" took like 13 hours using overclocked Ryzen 2700 with make -j12 && RAM tmpfs mount --bind /var/tmp/portage for builds (tmpfs which I have to say is SO fast wow) but i think it was all the lto linking that lengthened GCC compile time, I enabled only on GCC. Also, configuring packages is brutal! haha its the slowest line per line update, seconds apart lol
All in all took me like 3 or 4 days overtime, but so worth it  currently emerge-chrooting rust... 7 hours in xd

FilthyPitDog,
Well done!
Trying the mainline kernel is still on my TODO list.
The only things I would change in a QEMU chroot are to remove.
| Code: | QEMU_SOFTMMU_TARGETS="aarch64 arm x86_64"
QEMU_USER_TARGETS="aarch64 arm" |
You have an amd64 qemu-static installed in the chroot. Its what executes the arm64 files. If you build QEMU in the chroot like that, hopefully it will fail.
If were to work, your amd64 qemu-static will be replaced by an arm64 version.
If you have the RAM, | Code: | | PORTAGE_TMPDIR=/var/tmp/portage |
can be in tmpfs.
Mount it before you chroot. Likewise, repos and distfiles can be shared.
