Vyacheslav Egorov 5548d11f4c Revert "[vm/build] Workaround for ld 2.19 crash on ARM" 
This reverts commit e961aa565e.

Reason for revert: does not actually work

Original change's description:
> [vm/build] Workaround for ld 2.19 crash on ARM
>
> When producing ARM builds instruct llvm-objcopy to drop .ARM.exidx/extab
> sections. These sections don't contain any useful information (we don't use
> exceptions or unwind C++ frames and most of the dart binary is in fact not
> covered by them), however they have been seen to break dynamic linker in older
> glibc versions (pre 2.23) because .ARM.exidx ends up being positioned between
> .rel.dyn and .rel.plt sections while older versions of dynamic linker
> expect these two sections to appear one after another in the ELF file.
>
> Closes https://github.com/dart-lang/sdk/issues/41644.

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
