4fc3de624a Prepare this crate for more wasm32 compatibility 
This commit prepares the build script for a wasm32 target that doesn't use
Emcripten, notably forcing the `mem` feature to get activated and forcibly
ignoring the `c` feature, even if activated, for the wasm32 target.

0b2a017b94 Update rustbuild commentary 
Also use `cfg!(feature = "rustbuild")` instead of the environment
variable to ease grep-ability.

465ba28996 Update the gcc crate to 0.3.53 and disable compilation warnings 
They are inside the compiler-rt submodule, about which we don't have
direct control over.

ebcf7fac6a Compile ffsdi2 with rustbuild feature 
This is not used by LLVM/Rust, but is apparently used by gcc/C which jemalloc
can require at least.

e48cd1180b Use the Rust implementation of udivsi3 on ARM 
Although compiler-rt presumably has a more optimized implementation written in
assembly, it appears buggy for whatever reason, causing #173.

For now let's see if integration into rust-lang/rust will work with the
Rust-defined implementation!

6eeab2e62f floattidf, floatuntidf: ignore differences smaller than 2 in test 
Its possible that the generated f64 is different from the expected one
by one bit. This is legal when both values are equally close to the i128/u128.

some symbols on 32-bit Linux.
