From: Alex Bennée Date: Mon, 3 Feb 2020 09:09:17 +0000 (+0000) Subject: tests/docker: better handle symlinked libs X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5e33f7fead5;p=qemu.git tests/docker: better handle symlinked libs When we are copying we want to ensure we grab the first resolution (the found in path section). However even that binary might be a symlink so lets make sure we chase the symlinks to copy the right binary to where it can be found.
