Subject: [PATCH] fix prototypes of signal callbacks in the test suite

The signal callbacks are defined to take pointers as their arguments, but the
callbacks found in testsuite/gtk/builder.c are passing a GParamSpec by value
as the second argument.  This confuses and angers the compiler on ppc64el,
resulting in segfaults after return from the function due to stack-smashing
by the (completely-unused) argument.
