[Buildroot] [PATCH] Config.in: add BR2_DL_DIR_OPTS

[Yann E. MORIN <yann.morin.1998@free.fr>]

Markus, all,

On 2018-10-31 14:39 -0700, Markus Mayer spake thusly:
> Provide a simple mechanism to pass extra arguments to "mkdir" when
> creating download directories. This can be helpful if one needs the
> download directories to be writable multiple users ("shared download
> cache").

We eventually talked about this with Thomas, and we think a better
solution would be that the original umask of the user is saved before
re-entering make, and then exported so that dl-wrapper can use it when
doing the downloads.

Would you like to try and have a go at this alternate solution, instead?

Regards,
Yann E. MORIN.
