sh: Add 64-bit time types from kernel
Building uclibc 1.0.37 for SuperH architecture with linux-headers 5.10.7 fails at libpthread level due to missing time-related data structures, usually defined by the kernel. Define those missing data structures in SuperH-specific kernel_types.h. Context: building for sh4eb-r2d[1] and sh4-r2d[1] boards emulations for QEMU using the buildroot image generation tool. Regarding the issue, a patch[3] was already issued in the kernel some time ago, which aimed to solve precisely this problem. After coming up with a quick and dirty patch for buildroot modifying Linux headers[4], some discussion was sparked on the subject with Linux folks[5]. Some analyzing later, conclusion was that: 1) Previously mentioned patch[4] was fixing the symptom, not the ill 2) SuperH-specific code in uclibc could be patched instead, to solve the problem for other use cases (e.g. building just a toolchain) [1] https://git.buildroot.net/buildroot/tree/configs/qemu_sh4eb_r2d_defconfig?h=2020.02.9 [2] https://git.buildroot.net/buildroot/tree/configs/qemu_sh4_r2d_defconfig?h=2020.02.9 [3] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fc94cf2092c7c1267fa2deb8388d624f50eba808 [4] https://git.buildroot.net/buildroot/commit/?id=742f37de8d0e3797698411dfc6a63bd7e98aafe2 [5] https://patchwork.kernel.org/project/linux-sh/patch/20210123165652.10884-1-geoffrey.legourrierec@gmail.com/ Signed-off-by: Geoffrey Le GourriƩrec <geoffrey.legourrierec@gmail.com>
