This results in MozillaFirefox and kernel-default/pae/... build failure on i586 (we use x86_64 kernel for building). In the latter, pahole fails with for example like: [ 188s] ../scripts/link-vmlinux.sh: line 111: 16935 Segmentation fault LLVM_OBJCOPY="${OBJCOPY}" ${PAHOLE} -J ${PAHOLE_FLAGS} ${1} strace says: 1223 mmap2(NULL, 5783552, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0 <unfinished ...> ... 1223 <... mmap2 resumed>) = -1 ENOMEM (Cannot allocate memory)
