The Bootlin external toolchain file Config.in.options contains multiple occurrences of "select BR2_TOOLCHAIN_HAS_THREADS". See for example [1]. This file is generated by the support/scripts/gen-bootlin-toolchains script from the information published at [2]. Those multiple occurrences happens with toolchains having BR2_TOOLCHAIN_HAS_THREADS_DEBUG and/or BR2_TOOLCHAIN_HAS_THREADS_NPTL. Since the script uses the startswith() method, the _HAS_THREADS selection is also generated for _HAS_THREADS_DEBUG and _HAS_THREADS_NPTL. See [3]. This commit solve the issue by adding a '=' character to make sure the test will be distinct from other strings having the same prefix. Note: there is no functional problem due to those multiple selections, since it is allowed by Kconfig. This commit is simply cosmetic, for correctness.

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.
