The initial problem is that contrib/crc32vx is excluded in the Debian tarball, but adding it doesn't help due to the baseline: contrib/crc32vx/crc32_vx.c: In function 'crc32_le_vgfm_16': contrib/crc32vx/crc32_vx.c:79:17: error: '__builtin_s390_vec_insert' requires '-mvx' 79 | v0 = (uv2di)vec_insert(crc, (uv4si)v0, 3); | ^~~~~~~~~~ The patch below (which is a nop on other architectures) fixes the FTBFS.
