misc/cgo/test: skip test7978 when using gccgo

Browse Source 
Gccgo can only get a backtrace for the currently running thread, which
means that it can only get a backtrace for goroutines currently running
Go code.  When a goroutine is running C code, gccgo has no way to stop
it and get the backtrace.  This test is all about getting a backtrace
of goroutines running C code, so it can't work for gccgo.
