This should fix the following when statically linking host tools:
gcc .../tools/objtool/objtool-in.o -lelf .../tools/objtool/libsubcmd.a -static -o .../tools/objtool/objtool
.../bin/ld: .../sys-root/lib/libelf.a(elf_compress.o): in function `__libelf_compress':
.../libelf/elf_compress.c:113: undefined reference to `deflateInit_'
