Vyacheslav Egorov e961aa565e [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.
