Re: [PATCH] gnu: bootstrap-tarballs: Cross-compile for powerpc-linux-gnu.

Hello Carlos!

Happy new year!  :-)

Leo just reminded me of this patch on IRC, and I feel guilty that it
stood there for so long.  Apologies!

address@hidden (Carlos Sánchez de La Lama) skribis:

I ended up splitting it in 3 patches (gcc, linux-libre, and
glibc-dynamic-linker) that I just pushed to ‘core-updates’.  I also
added copyright lines for you where appropriate.  Hope that’s fine!

Sounds like a good plan.

Commit 9410a5aa916035bb4d7f032a5fe81cfb497887c8 adds powerpc-linux-gnu
cross-builds for Hydra (though Hydra is currently busy with the
‘staging’ branch.)

Awesome!

Sorry again for the delay and the frustration it probably entailed.

Cheers,
