Collected errors:

• pkg_hash_check_unresolved: cannot find dependency libgcc for libc
• pkg_hash_fetch_best_installation_candidate: Packages for libc found, but incompatible with the architectures configured
• opkg_install_cmd: Cannot install package libc.
  make[2]: *** [Makefile:218: package_install] Error 255
  make[1]: *** [Makefile:161: _call_manifest] Error 2
  make: *** [Makefile:322: manifest] Error 2

Start by reproducing the request for profile glinet,gl-mt6000 on the ASU service and tracing package-index generation through the imagebuilder manifest step shown in the log. Check why the mediatek/filogic package indexes select incompatible libc and libgcc packages; done means the attended sysupgrade build completes without the unresolved dependency errors.
