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.
