Yup. In older glibc versions, those functions were in librt, but have since 
moved to the main libc. It's unsurprising that software quickly forgot to add 
the flags that aren'tneeded anymore.

No, because this isn't qmake. This is trying to build gn, a generator that 
will create the ninja files for building chromium.

I suggest you install a system-wide gn. You can fix its build manually, if 
necessary. So long as "gn" exists in PATH, qtwebengine won't try to rebuild
