While trying to build kernel (4.15) with support Ftrace and debug info, I am getting the following error:

       FAILED: load BTF from vmlinux: No such file or directory
       Makefile:1160: recipe for target 'vmlinux' failed

This is what I am trying:

       $ ./scripts/config -e CONFIG_FTRACE
       $ ./scripts/config -e CONFIG_DEBUG_INFO
       $ ./scripts/config -e CONFIG_DEBUG_INFO_DWARF5
       $ ./scripts/config -e CONFIG_BPF_SYSCALL
       $ ./scripts/config -e CONFIG_DEBUG_INFO_BTF
       $ ./scripts/config -d CONFIG_DEBUG_INFO_REDUCED
       $ yes "" | make oldconfig
       $ make -j$(nproc) Image dtbs modules

This issue seems to be different from this one:

"FAILED: load BTF from vmlinux: Unknown error -2make: *** [Makefile:1162: vmlinux] Error 255", while compiling kernel-5.9.1
