Support #5297
install.mk : install-runtime-target added for conveneice
automatically push runtime library to android device
test.mk : expanded to support android test automation with adb
compiletest : expanded to support android test automation with adb
Moving the trait into `core` allows it to be added to the `num::Float` trait.
I have also added and `assert_approx_eq!` macro. This is useful fo making approximate assertions on types that implement the `ApproxEq` trait.
Examples:
~~~rust
// using the default epsilon value
assert_approx_eq!(1.0000001f, 1.0f);
// using a custom epsilon value
assert_approx_eq!(1.000001f, 1.0f, 1.0e-5);
// fails with: "left: 1.00001 does not approximately equal right: 1"
assert_approx_eq!(1.00001f, 1.0f);

transitional patch to resolve compile/link failure on android
after #6161 landed, I've encountered below errors since android does not support glob in libc.

Since android does not have `glob.h`, `glob_t` definition comes from
https://groups.google.com/forum/?fromgroups=#!topic/android-ndk/vSH6MWPD0Vk#6100 should be resolved.
In commit d7f5e43 "core::rt: Add the local heap to newsched tasks",
local_malloc and local_free have become rather big and their forced
inlining causes quite a bit of code bloat. Compile times for crates
affected by the bloat (e.g. rustc) improve, while others (e.g. libstd)
seem to be unaffected, so I guess the inlining doesn't gain us much.
Sizes:
```
| librustc | libsytax
---------------|–-----------|------------
with inlining | 18,547,824 | 7,110,848
w/o inlining | 15,092,040 | 5,518,608

I just had `git apply` fix most of them and then did a quick skim over the diff to fix a few cases where it did the wrong thing (mostly replacing tabs with 4 spaces, when someone's editor had them at 8 spaces).
