I've applied, but after splitting this in 3 commits:

- Adding the missing BR2_USE_MMU dependency (it's a fix, even though it
  doesn't really have an impact)
- Adding the missing gcc >= 6 dependency (it's a fix)
- Re-enabling on all CPU architectures (it's not a fix)

Indeed, the first two are eligible for LTS, while the last one isn't.

Thanks!

Thomas
