On Gentoo::Prefix I have rather long $EPREFIX path. Some build system is brave and uses the full path to derive a filename, so it ends up with an Error: Filename too long.

BTW I am on NFSv4 filesystem: nfs4 rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard
A workaround for me is to use a different filesystem mkdir /dev/shm/mmokrejs; PORTAGE_TMPDIR=/dev/shm/mmokrejs emerge ${crap} The above patch indeed works if one reserves a position for the erroneous extra dot character. So I decreased the number from 251 to 250 and now the patch work on NFS too. BTW, it introduces a warning but luckily works: [123/195] CXX src/gn/ninja_action_target_writer.o ../../../../qtwebengine-everywhere-src-6.5.2/src/3rdparty/gn/src/gn/ninja_action_target_writer.cc: In member function ‘std::string NinjaActionTargetWriter::WriteRuleDefinition()’: ../../../../qtwebengine-everywhere-src-6.5.2/src/3rdparty/gn/src/gn/ninja_action_target_writer.cc:130:78: warning: comparison of integer expressions of different signedness: ‘int’ and ‘const std::__cxx11::basic_string<char>::size_type’ {aka ‘const long unsigned int’} [-Wsign-compare] 130 | while (rspfile.length() > 250 && (pos = rspfile.find_last_of(delimiter)) != std::string::npos) | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~
The extra dot issue is fixed by https://codereview.qt-project.org/c/qt/qtwebengine-chromium/+/495236 patch.
