iOS cross compiling support

[James Gregurich]

archs =  armv6 & armv7.

triplet to compile icu for iOS:  arm-apple-darwin.


I'm not sure how cross-compiling works in the general case, but the way Apple has it set up for their stuff, you use the compiler from the sdk. I think the default for iOS is currently llvm-gcc. However, it wouldn't be surprised if it was switched to clang for xcode 4. Bottom line: you explicitly pick the target sdk and a compiler in that sdk.

The question is....is there a generic way to derive a triplet from the sdk and compiler....or should one be forced to supply part of the triplet as a configuration option if he isn't targeting specifically an iOS sdk?
