Yep, I've done as part as Gustavo review of the patches.

Ok, thanks.

Patch applied.

It looks good, but I'd like to have someone ACK or test the patch.
Yann, Gustavo, Arnout?

Agreed.

So the problem is that one cannot simply do

  $(O)/host/usr/bin/ccache --max-size=5G

because the BUILDROOT_CACHE_DIR is passed as an environment variable,
and defined by the Buildroot Makefile, so if you want to interact
manually with ccache, you'd have to manually pass BUILDROOT_CACHE_DIR.

This explains why the patch was proposing this CACHE_OPTIONS idea, I
guess. I don't have much other ideas here, though.

Best regards,

Thomas
