[Buildroot] [PATCH 1/1] package/rpi-userland: add support for aarch64 build

[Yann E. MORIN]

Christian, All,

On 2020-08-18 12:11 -0700, Christian Stewart spake thusly:
> Tested on Pi4 Model B (aarch64).

There was previous proposal for this:

    http://lists.busybox.net/pipermail/buildroot/2020-June/285000.html
    http://lists.busybox.net/pipermail/buildroot/2020-January/271588.html

where it wsa noticed and pointed out that not all libraries were
installed for tghe 64-bit variants, and that parts of the 64-bit
support even git reverted upstream:

    https://github.com/raspberrypi/userland/commit/f97b1af1b3e653f9da2c1a3643479bfd469e3b74

How does that patch address these issues?

Regards,
Yann E. MORIN.
