Not saying a thing about Gentoo's build scripts--since I know nothing of 
what they say--but a MySQL upgrade will never cause a need for a MythTV 
recompile.

That said, a MySQL upgrade may well cause a need for a Qt (specifically 
Qt-MySQL) recompile (otherwise, you may well get "commands out of sync" 
or segfaults or whatever).  And, assuming you're using the same version 
of Qt, you shouldn't need to recompile MythTV.  If, however, you change 
Qt/Qt headers, you probably need to recompile MythTV.

So, upgrading MySQL doesn't directly cause a need to recompile MythTV.  
But it may cause a need to recompile the (much-larger, 
much-longer-to-compile) Qt framework.
