The "arches" dict lists the architectures for which Bootlin toolchains
are available, along with the corresponding Buildroot conditions for
those architecture variants.
However, there is nothing that checks that such architectures really
have Bootlin toolchains available. Even if no toolchain is available,
the architecture is considered as support, and will be listed in the
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_ARCH_SUPPORTS option, making menuconfig
believe that some Bootlin toolchain is available for the selected
architecture variant.
This is currently the case with the "mips64" architecture (as
identified by the Bootlin toolchains project). Such toolchains have
been made obsolete in toolchains.bootlin.com and replaced by the
mips64-n32 toolchains. But "mips64" is still listed in "arches",
causing this architecture to be considered as having Bootlin
toolchains available.
To avoid this to happen in the future, this commit adds a check that
verifies that an architecture listed in "arches" really has at least
one toolchain available.

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
