Build script for archlinux instructionset enabled repos.
All packages are build with -march=<cpu-set> and -O3. Some packages will not build with -O3, they will just be provided from the official repos as usual.
## Check your system for support
**Important**: Before you enable any of these repos, check if your system supports x86-64-v3. You can do that with `/lib/ld-linux-x86-64.so.2 --help`. If you don't check beforehand you might be unable to boot your system anymore and need to downgrade any package that you may have upgraded.
Example output snippet for a system supporting up to `x86-64-v3`:
```
Subdirectories of glibc-hwcaps directories, in priority order:
x86-64-v4
x86-64-v3 (supported, searched)
x86-64-v2 (supported, searched)
```
## Enable Repos
To enable these complement repos you need to add them above the regular repos in `/etc/pacman.conf`
### Example pacman.conf
