It's complaining about libelf.h but I have that, so I don't know where it is looking other than /usr/include/libelf.h, which exists. Maybe the tool isn't setup (ready) for cross-compiling?
Here's the build output for objtool:
<stdin>:1:10: fatal error: libelf.h: No such file or directory compilation terminated. elf.c: In function ‘read_sections’: elf.c:273:9: error: ‘elf_getshnum’ is deprecated [-Werror=deprecated-declarations] 273 | if (elf_getshdrnum(elf->elf, §ions_nr)) { | ^~ In file included from /usr/include/gelf.h:32, from /work/lnx/next/linux-next-20230203/tools/objtool/include/objtool/elf.h:10, from elf.c:22: /usr/include/libelf.h:310:12: note: declared here 310 | extern int elf_getshnum (Elf *__elf, size_t *__dst) | ^~~~~~~~~~~~ elf.c:278:9: error: ‘elf_getshstrndx’ is deprecated [-Werror=deprecated-declarations] 278 | if (elf_getshdrstrndx(elf->elf, &shstrndx)) { | ^~ /usr/include/libelf.h:322:12: note: declared here 322 | extern int elf_getshstrndx (Elf *__elf, size_t *__dst) | ^~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[4]: *** [/work/lnx/next/linux-next-20230203/tools/build/Makefile.build:96: /work/lnx/next/linux-next-20230203/PPC32/tools/objtool/elf.o] Error 1
