[Pkg-rust-maintainers] Bug#905623: cargo: Please include patch to disable incremental tests on sparc64

[John Paul Adrian Glaubitz]

Source: cargo
Version: 0.28.0-1~exp2
Severity: normal
Tags: patch
User: debian-sparc at lists.debian.org
Usertags: sparc64

Hello!

As incremental builds currently don't work on sparc64 [1], we have
disabled them completely with a patch in cargo. With cargo 0.28,
upstream added tests for incremental building which cause cargo
to FTBFS on sparc64 [2].

The attached patch disables the incremental build tests on sparc64
for cargo and thus work-around the problem. Please include this
patch in the next upload of cargo.

Thanks,
Adrian
