For
```
SECTIONS {
text.0 : {}
text.1 : {}
text.2 : {}
} INSERT AFTER .data;
```
the current order is `.data text.2 text.1 text.0`. It makes more sense to
preserve the specified order and thus improve compatibility with GNU ld.
For
```
SECTIONS { text.0 : {} } INSERT AFTER .data;
SECTIONS { text.3 : {} } INSERT AFTER .data;
```
GNU ld somehow collects sections with `INSERT AFTER .data` together (IMO
inconsistent) but I think it makes more sense to execute the commands in order
and get `.data text.3 text.0` instead.
