So umm yeah... I have been tweaking my .config a bit but nothing too weird, but tc is throwing errors in the final build phase when I compile for ath79/generic. Tc is pulled in by a dependency tree that starts with luci-app-sqm at the top.
I'm relying on the PER_DEVICE_ROOTFS functionality to build different images for multiple devices under ath79/generic. That worked fine so far (I run a 19.07 HEAD build every few weeks to keep up to date).
I tested an ipq40xx 19.07 build (also with PER_DEVICE_ROOTFS and tc etc. built modularly) and that build compiles just fine somehow.
Error the buildroot throws:
Collected errors:
* satisfy_dependencies_for: Cannot satisfy the following dependencies for tc:
* kmod-sched-core
* libelf1
* opkg_install_cmd: Cannot install package tc.
make[2]: *** [package/Makefile:68: package/install] Error 255
make[2]: Leaving directory '/var/media/data/code/lede/19.07'
make[1]: *** [package/Makefile:108: /var/media/data/code/lede/19.07/staging_dir/target-mips_24kc_musl/stamp/.package_install] Error 2

make: *** [/var/media/data/code/lede/19.07/include/toplevel.mk:227: world] Error 2
Both kmod-sched-core and libelf1 are [m] in the .config so they're built as modules (and should be pulled in). I'm not sure what's going wrong here.
