bug#70865: Unable to generate a bootable image for pinebook pro

[Richard Sent]

Hi Guix!

When building a system image for the pinebook pro, the image either
fails to build or fail to boot. This occurs when when using the
pinebook-pro-barebones-raw-image defined in the Guix repository.

When --system=aarch64-linux is not passed, the image build fails when
cross compiling packages.

When --system=aarch64-linux is passed (enforcing QEMU builds for
packages instead of attempting cross compilation), the image builds but
the Pinebook Pro does not appear to detect it and will fall back on
eMMC.

Per the blog post on
https://othacehe.org/distributing-guix-system-pinebook-pro-images.html,
building a pinebook pro system image should be as simple as the first
command. When package compilation errors occurs, the user should be able
to fall back on the second command.

Below is the tail of the log when cross compiling gawk-mesboot:
