As long as I am using CONFIG_DEBUG_INFO_BTF=y with LLVM/Clang
I have noticed the below macros where defined unconsistently.

See here pahole latest Git...

[ pahole:dwarf_loader ]

/* Match the define in linux:include/linux/elfnote.h */
#define LINUX_ELFNOTE_BUILD_LTO                0x101

...and latest Linus v6.2-rc4+ Git:

[ linux:include/linux/elfnote-lto.h ]

#define LINUX_ELFNOTE_LTO_INFO         0x101

Ya, LINUX_ELFNOTE_BUILD_LTO is initially proposed macro name but later
the formal kernel patch used LINUX_ELFNOTE_LTO_INFO. Could you submit
a pahole for this so it is consistent with kernel? Thanks!

Fix this by syncing the pahole macro with the one from linux-kernel.
