Since commit947dbc92a2the Bootlin stable toolchain uses headers 5.4, which can lead to build outputs incompatible with older kernels. Update to the latest 5.4 kernel to avoid this. The kernel config is updated according to the requirements of current Docker, runc, and crun. Additionally switch the CPU of the test VM to Haswell, to avoid dockerd failing to start with a "This program can only be run on AMD64 processors with v3 microarchitecture support" error.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
