- remove /usr/include from the include path since the iOS SDK provides the correct version
- `_NSGetEnviron()` is private and not available on iOS
- `.align` without an argument is not allowed with the Apple tools. 2^2 should be the default alignment
- ignore error messages for XCode < 5
- pass include path to libuv

This commit resumes management of the stack boundaries and limits when switching
between tasks. This additionally leverages the __morestack function to run code
on "stack overflow". The current behavior is to abort the process, but this is
probably not the best behavior in the long term (for deails, see the comment I
wrote up in the stack exhaustion routine).

Closes #5643
This also removes the need to pass noexecstack to gcc, but that wasn't
actually working anymore.

As per #2521. Inlining seems to improve performance slightly:
Inlined Not Inlined
x86: 13.5482 14.4112
x86_64: 17.4712 18.0696
(Average of 5 runs timed with `time`)
```Rust
fn foo() -> int {
int::from_str(~"28098").unwrap()
}
fn main() {
for 1000000.times {
foo();
foo();
foo();
foo();
foo();
}
}
```
All run on:
Linux 3.2.0-0.bpo.4-amd64 #1 SMP Debian 3.2.35-2~bpo60+1 x86_64 GNU/Linux
The MIPS and ARM bits I didn't inline since I'm not as familiar with them and I also can't test them. All green on try.
