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.
