Is there a Gentoo Way (tm) for testing whether a specific language
module is available in gcc?

++

The specific case is gcj - I had "gcj" in my use flags from way back,
but I just got a field report from someone testing an ebuild I've
prepared saying:

My ebuilds respond to USE=gcj, but I obviously need to do a dependency
type check. Obviously something like 

	test -x `which gcj`

Would serve, but is there some magic (gcc-config or better yet a
dependency?) which would help?

[It's almost like there should be something like virtual/gcj provided by
gcc if gcc is compiled with Java enabled... Hm]
