When a new gcc version is introduced, for example gcc 15 in
commit [1], it should have also added a "depends on
!BR2_ARCH_NEEDS_GCC_AT_LEAST_15" to the previous gcc version.
This logic is described for external toolchains in commit [2],
for example. The internal Buildroot toolchains should have the
same logic. This logic existed for previous gcc version. See for
example the removal of gcc 12 in commit [3].
There is usually no problem, because all the three latest active gcc
versions supports all CPUs present in Buildroot.
However, the commit [4] recently added the support for the Arm
Cortex-A720 CPU, which needs at least gcc 14. Since there is no
logic preventing the selection of the gcc version, it is possible
to select an unsupported gcc version (i.e. gcc 13).
In such a case, the host-gcc-initial package configuration fails
with output:
Unknown cpu used in --with-cpu=cortex-a720
This commit fixes the issue by adding those missing dependencies.

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
