Android update

[joakim-noah]

Pull in some necessary declarations from bionic, exclude some CRuntime_Glibc definitions, add ARM support extracted from my work with ldc, and replace all uses of Android with CRuntime_Bionic or linux.

Ping, no problems with the auto-tester for three weeks. I think this and #1384, which has been sitting for more than five months, can be merged.

Auto-merge toggled on

Not too fond of duplicating function implementations, though. I get Walter's/… point of making platform support explicit for bindings, but at some point, it must be better to use a common implementation to avoid code duplication.

I'd like to get this and a couple other PRs merged into the ldc branches. Should I do that or would you prefer to do it?

[dnadlinger]

Just go ahead and merge it, I'd say.

Regarding function implementations, I guess you're talking about __tls_get_addr? The two function prototypes are slightly different, because X86 uses an extra underscore and I think the dmd patch dereferences the passed-in pointer, so only the last three lines are the same. Rather than extract those out, I just cut-n-pasted it.

Ah, thanks, I see now – it was quite late at night, and they looked visually similar.
