Comment:
It's one thing to make things needless complicated to support some unsupported, nonstandard use. It's another thing to make simple accommodations that preserve existing workflows. Unless I'm missing something, the accommodation looks as simple as changing
```
if [ "${archs// /}" = "noarch" ]; then
```
to
```
if [ "${archs// /}" = "noarch" -a -n "$XBPS_ALLOW_NOARCH" ]; then
```
