A new version of Android NDK is available. There are no tarballs for legacy toolchains available, but they are mentioned in description. I've posted a bug asking whether it is intentionally: http://code.google.com/p/android/issues/detail?id=64213&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars I'll wait for answer for some time and then proceed with version bump.
Created attachment 366792 [details] android-ndk-9c.ebuild ebuild for a new NDK. It has no legacy toolchains included as upstream does not provide any. I do not think they will add them (it seems they just forgot to change text on the web-page), so this ebuild can be added to the tree. I've tested it on x86 and amd64.
Seems it's already bumped earlier today http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-util/android-ndk/android-ndk-9c.ebuild?view=log
Doug Goldstein: thanks for your quick reaction.
