Due to compiler deficiences, gcc on ARC and Blackfin doesn't define _REENTRANT, which the latest version of the ax_pthread.m4 autoconf-archive macros looks at to determine whether thread support is available or not. Fixing the compilers is definitely the right thing to do, but it's not doable for pre-built external toolchains like the Blackfin one, so for now, we simply define _REENTRANT manually on ARC and Blackfin. If more packages are affected by this problem, a more general solution will have to be found.

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
