Fabrice Fontaine 8cb0f6e011 toolchain/Config.in: update BR2_TOOLCHAIN_HAS_LIBATOMIC dependencies ... Update BR2_TOOLCHAIN_HAS_LIBATOMIC dependencies to avoid the following build failure with libopenssl and BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_ARMV7M_UCLIBC_STABLE: /home/buildroot/autobuild/run/instance-2/output-1/host/opt/ext-toolchain/arm-buildroot-uclinux-uclibcgnueabi/bin/ld.real: ./libcrypto.a(libcrypto-lib-threads_pthread.o): in function `CRYPTO_atomic_or': threads_pthread.c:(.text+0xfa): undefined reference to `__atomic_is_lock_free' libatomic is available since gcc 4.8, when thread support is enabled. However, the gcc logic in libatomic/configure.tgt does not recognize "uclinux" as a valid OS part of the target tuple, and therefore it does not build libatomic. The "uclinux" part of the tuple is used by Buildroot when BR2_BINFMT_FLAT=y [1]. This broken logic has only been fixed for arm since gcc 10.1.0 [2]. Indeed, bootlin armv7m is an uclibc toolchain compiled with atomic support through libatomic.
