Yes, you are right.
If we compile current `next` natively, we have `linux-headers-
mainline_5.4.203+r0_armhf.deb` package with 32-bit ARM binaries inside the
package (in `scripts` dir). Buf if we crosscompile it, we have 64-bit x86-64
binaries in the package with the same name.
You patches fix this by generating `linux-kbuild-
mainline_5.4.203+r0_armhf.deb` (with 32-bit ARM binaries) and `linux-kbuild-
mainline-cross_5.4.203+r0_armhf.deb` (with 64-bit x86-64 binaries).
I'm just not sure that this "-cross" package should be with `armhf` prefix
(e.g., now it has control file with "Architecture: armhf" field).
