So far, BR2_UCLIBC_TARGET_ARCH had a value for all
architectures... except for ARM64. Its value is passed as ARCH= when
building uClibc... which is currently empty:
/usr/bin/make -j33 -C .../build/uclibc-1.0.41 ARCH="" CROSS_COMPILE=".../host/bin/aarch64-buildroot-linux-uclibc-"
And also in uclibc.mk, when we inject the architecture in uClibc's
.config:
$(call KCONFIG_ENABLE_OPT,TARGET_$(UCLIBC_TARGET_ARCH))
$(call KCONFIG_SET_OPT,TARGET_ARCH,"$(UCLIBC_TARGET_ARCH)")
We enable TARGET_ (which doesn't exist) and set TARGET_ARCH to the
empty string.
Nobody noticed so far, and it happens to work because aarch64 is the
first architecture in the choice of architectures in
extra/Configs/Config.in in the uClibc code. So, when the architecture
is not specified, aarch64 is used.
As we are about to add some logic in uclibc.mk that will use
BR2_UCLIBC_TARGET_ARCH, we noticed this missing definition.

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
