Bug#683782: gccgo: please Recommend: binutils-gold on x86

[shawn <shawn@jengr.tk>]

Source: gcc-4.7
Version: 4.7.1-6
Severity: normal

gccgo requires binutils-gold in order to fully use gcc's split stack feature.
As this feature is heavily used by the core language constructs of go,
(namely "goroutines", which are conceptually light-weight threads)
and has large performance inpacts, gccgo should Recommend: binutils-gold. (at least)

gcc currently only supports split stacks on x86, so this could be limited to
x86 architectures until more architectures support split stack.
(and in later gcc-4.8, etc)
