Romain Naour c43f12293d package/rustc: rust >= 1.73.0 needs cmake >= 3.20
The bump to rust 1.74.1 [1] introduced a regression on host using
cmake < 3.20 since the llvm libraries used in rust compiler was
bumpted to llvm 17 [2] and now requires cmake >= 3.20 [3].

Select BR2_HOST_CMAKE_AT_LEAST_3_20 to build host-cmake when needed.

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.
