Since its introduction in commitb05e74ff92in 2013, numactl has had an explicit list of architectures that it supports. Interestingly, this list does not include ARM, and now that rt-tests unconditionally needs numactl, it meant the rt-tests package was no longer available on ARM. Further investigation revealed that there is nothing in recent versions of numactl that appears to be architecture-specific. It does build with all of Buildroot toolchains currently used in the autobuilders. The only necessary changes are: * Exclude no-MMU architectures, as madvise() is used in the code base, and this is not available on no-MMU architectures. * Make sure to use -latomic when needed, as some atomic operations are used. * Backport a patch that fixes the .symver usage, which only affects really old gcc versions: only the old ARM Sourcery toolchain was affected by this. Newer gcc versions support the gcc "symver" attribute, so that the code that directly emits the assembly .symver directive is not invoked. With these changes, numactl builds successfully on all our supported toolchains. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Yann E.
