This happens when a header file, elf.h, on "your host machine" does not have definitions of EM_AARCH64 nor R_AARCH64_ABS64 because "recordmcount" is a binary utility on host(x86), not target. It is very likely for most distros. (I mentioned this in the cover letter, but the description might not be clear.)
Possible solutions are:
- Define both macros directly in scripts/recordmcount.c
- Use perl version of recordmcount
Currently I take 1), but it is a workaround. 2) should work with my current patch, too. But you need to remove HAVE_C_RECORDCOUNT from arm64/Kconfig.
Which one do you prefer? I will include a fix for 1) in the next revision, anyway.
Or even option 3)
3) I can update the main Makefile to check to see if EM_<ARCH> exists in the elf.h header, and if not, we use the perl version and undef HAVE_C_RECORDMCOUNT.
