No.  Your error is a build failure, not a runtime failure. See:

/home/tkloczko/rpmbuild/BUILD/webkitgtk-2.39.5/Source/JavaScriptCore/runtime/Options.cpp: In static member function ‘static void JSC::Options::notifyOptionsChanged()’:
/home/tkloczko/rpmbuild/BUILD/webkitgtk-2.39.5/Source/JavaScriptCore/runtime/Options.cpp:665:30: error: ‘supportsAVX’ is not a member of ‘JSC::MacroAssembler’
  665 |         if (!MacroAssembler::supportsAVX())
      |                              ^~~~~~~~~~~

This means something is not set up to build the code correctly.  Since you're trying to build for redhat, I'll let the redhead folks look at this.
