I'm sorry, but I don't really understand what you're saying.

If you are building the Linux kernel with Buildroot, so you definitely
have a directory called output/build/linux-<version>/ which contains
the kernel source code, the kernel configuration (.config file) and
all the object files/images that result from a kernel build.

If you don't have this folder, then you are definitely not building the
Linux kernel with Buildroot.
