Manually adding -lstdc++fs to the linker command for the generated /qtbuild/src/tools/syncqt/configure_time_bins/CMakeFiles/rules.ninja file, and then running ninja inside of /qtbuild/src/tools/syncqt/configure_time_bins works, but a new configure will of course overwrite this.
So it seems that for GCC 8, one must manually add -lstdc++fs. This was always the case, but only became an issue since syncqt switched from Perl to C++.
