Since 392b0a26f5 (toolchain-external: default BR2_TOOLCHAIN_EXTERNAL_PATH
to empty), calling 'make clean' or similar can yield a spurious stderr
message:
dirname: missing operand
Try 'dirname --help' for more information.
Which is definitely baffling and unsettling...
It turns out that it is pretty trivial to reproduce, and this defconfig
is just enough:
$ cat my-defconfig
BR2_TOOLCHAIN_EXTERNAL=y
$ make BR2_DEFCONFIG=$(pwd)/my-defconfig defconfig
$ make clean
dirname: missing operand
Try 'dirname --help' for more information.
[--snip--]
This is because the cross-compiler is not found in the PATH (and for
good reasons, I don't have it in the PATH, not even at all).
So, when the cross-compiler is not found in the path, we simply
continue as if all was good, and postpone the check to much later,
when we try to copy the toolchain libs...
So, use a make construct rather than calling to the shell: $(dir ...)
does not whine if passed nothing.

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