[Pkg-rust-maintainers] Bug#839643: src:rustc: FTBFS on ppc64el

[Erwan Prioul]

Hi,

I've been able to build the rust package on ppc64el with the attached patch.
In the patch:
 * workaround to avoid issue with the tests smoke_dtor and test_typed_arena_drop_small_count: no optimization on ppc64el
 * add ignore flags to asm test files that have no meaning for ppc64el
 * add a reference to a library in a makefile

Thanks for considering the patch.
Erwan.
