Collected errors:

• check_data_file_clashes: Package libustream-openssl20201210 wants to install file /builder/build_dir/target-mipsel_24kc_musl/root-ramips/lib/libustream-ssl.so
  But that file is already provided by package * libustream-mbedtls20201210
• opkg_install_cmd: Cannot install package luci-ssl-openssl.
  make[2]: *** [Makefile:234: package_install] Error 255
  make[1]: *** [Makefile:171: _call_manifest] Error 2
  make: *** [Makefile:349: manifest] Error 2

Start with the supplied ASU request and STDERR output, especially the package conflict between libustream-openssl20201210 and libustream-mbedtls20201210. Inspect the image build flow around Makefile lines 234, 171, and 349, then reproduce the request against the 24.10 ramips/mt7621 profile. Done means the requested image builds without the reported file clash.
