With dev-qt/qtwebengine there is seriuos problem using distcc with cross architecture builds. It ignores during build make.conf and explicit -march which causes failure to compile with distcc with different architecture than host of portage for which package is build. This package is very big so compilation on embedded device takes days instade of hours with distcc and fast remote server. Reproducible: Always Steps to Reproduce: On arm64 host make.conf CC=clang CXX=clang++ CHOST="aarch64-unknown-linux-gnu" CFLAGS="--target=aarch64-unknown-linux-gnu -pipe -march=armv8-a+crc+simd+crypto -mcpu=cortex-a72+crc+simd+crypto" CXXFLAGS="$CFLAGS" Actual Results: During compilation with distcc custom cflags are missing and march too which will at least generate wrong arch code ar fail at all

Thank you for the report. We need to have all information at hand before ticket assignment. That is why I ask you to * attach the logs and * paste the emerge info as described on https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket Please reopen this ticket (Status:UNCONFIRMED) afterwards.
Man You can produce it for Yourself it is reproductible always on every architecture. During build clang have missing --target=.... based on CHOST from make.conf without which DISTCC can't compile with cross architecture. emerge info I attached , but build log I dont have time to build brokend package for next few days. emerge --info Portage 2.3.99 (python 3.6.10-final-0, default/linux/arm64/17.0/systemd, gcc-10.1.0, glibc-2.31-r2, 4.4.154-1124-rockchip-ayufan-ged3ce4d15ec1 aarch64)
