The BR2_ARCH_NEEDS_GCC_AT_LEAST_X guards were added in commit [1] for toolchain-external-custom gcc versions from 4.8 to 12. No guard was added for gcc 13 because is was the latest version at that time (and the symbol BR2_ARCH_NEEDS_GCC_AT_LEAST_14 was not available at that time). Then, commit [2] and [3] added gcc 14 and 15 without adding guards. In order to prevent a Buildroot user selecting an external custom toolchain that does not support a selected CPU, this commit adds all the missing guards.

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.
