Re: [Buildroot] [PATCH 1/1] package/zfs: fix cross-compilation

[Alexander Mukhin <alexander.i.mukhin@gmail.com>]

Yann, All,

Noticed the same issue on x86-64 without cross-compiling. Here again the host
compiler was used instead of toolchain. The build failed because the host
compiler was older and did not support some fancy flags.

Host: Debian 11.7 x86_64
Host gcc: 10.2.1
Toolchain: x86-64--glibc--bleeding-edge-2022.08-1
Toolchain gcc: 12.2.0

The patch proposed by Michael Zimmermann fixed the issue.
