Stephen and 0-DAY CI Kernel Test Service reported broken cross build
for arm (arm-linux-gnueabi-gcc (GCC) 9.3.0), with following output:
/tmp/ccMS5uth.s: Assembler messages:
/tmp/ccMS5uth.s:69: Error: unrecognized symbol type ""
/tmp/ccMS5uth.s:82: Error: unrecognized symbol type ""
Having '@object' for .type diretive is wrong because '@' is comment
character for some architectures. Using STT_OBJECT instead that should
work everywhere.
Also using HOST* variables to build resolve_btfids so it's properly
build in crossbuilds (stolen from objtool's Makefile).
