That's good news. :)

I hope you're enjoying your vacation.

I guess anything built between the upload of the broken glibc and the fixed
one needs to be rebuilt.
Looking at the Build-Attempted section of the sh4 buildd, almost all seem
to be caused by this problem and should be given back, e.g.:
 * liblouisxml (glib2.0, already fixed)
 * sqlsmith (after postgresql-9.6 is rebuilt)
 * usbprog (after libgtk2.0-0 is rebuilt)
 * pdftk (after libgtk2.0-0 is rebuilt)
