build error for kernel

The thing about building linux kernel is i have no idea where the error is and it does not tell clearly which file/line the error is coming from:
For example:

1)
Makefile:69: but there are so many makefiles in kernel source, it is impossible to tell which one?

2) make: *** [Makefile:1437: tools/objtool] Error 2
This above make one to believe it is a makefile in tools/objtool folder but there is a Makefile in there but it only has 71 lines.

WTF??

sudo make -j64
mkdir -p /home/nonroot/extdir/gg/git/kernelbuild/5.14.0-480.el9.x86_64/tools/objtool && make O=/home/nonroot/extdir/gg/git/kernelbuild/5.14.0-480.el9.x86_64 subdir=tools/objtool --no-print-directory -C objtool
