Sample Go code that doesn't link with DragonEgg
Compiling and linking virtually any Go program with DragonEgg results in a
failure to find __builtin_init_heap_trampoline:
$ gccgo --version
gccgo (Ubuntu/Linaro 4.7.2-2ubuntu1) 4.7.2
Copyright (C) 2012 Free Software Foundation, Inc.

$ gccgo trampoline.go -o trampoline
$ gccgo -fplugin=/usr/local/lib/dragonegg.so trampoline.go -o trampoline
/tmp/ccpimsLI.o:trampoline.go:function main.main: error: undefined reference to
'__builtin_init_heap_trampoline'
collect2: error: ld returned 1 exit status
It seems that this symbol is being used when compiling closures with nontrivial
bodies (i.e., that can't be optimized out). Only very simple Go programs work
with DragonEgg.
