crossdev: change USE=vtv to whitelist |
| 9 |
|
| 10 |
Gentoo profiles enable vtv only for x86, amd64, arm and arm64. |
| 11 |
vtv is known to be broken at least for: |
| 12 |
- musl libc |
| 13 |
- bare metal targets |
| 14 |
- powerpc, powerpc64 (compiler SEGISEGVs: bug #618786) |
| 15 |
- hppa, ia64 (missing vtv crt* files) |
| 16 |
|
| 17 |
User can still explicitly enable vtv by tweaking |
| 18 |
/etc/portage/package.use/cross-${CTARGET} |
| 19 |
