Since commit [1], the autobuilder script generates fully random configurations that can trigger configurations that were not tested before. Here, the toolchain build with uClibc-ng without threads support (BR2_PTHREADS_NONE=y) fails to build due to a missing pthread.h header: ../../../libgcc/generic-morestack-thread.c:42:10: fatal error: pthread.h: No such file or directory 42 | #include <pthread.h> This issue was actually fixed by this commit [2] adding a patch for gcc 4.8, 4.9, 5.3. But it get lost when gcc 6 was added to Buildroot [3]. Since then the issue was present in Buildroot but has not been noticed.

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.
