1.17.0 armv7 fails in debuginfo-gdb test macro-stepping.rs

[infinity0]

See https://buildd.debian.org/status/fetch.php?pkg=rustc&arch=armhf&ver=1.17.0%2Bdfsg2-4&stamp=1497504124&raw=0 - similar to #37225 but for armv7.

For the time being, I'll disable this test for armv7 in Debian, like how it already is disabled for aarch64.

Triage: Does this test still fail? If yes, I'm still not sure this is worth keeping an issue open for? After all, this is a Tier 2 target, so tests are not guaranteed to pass. I agree it made sense to report this 6 years ago because someone might have showed up and said "oh it fails? I'll fix it then". But since that hasn't happened for 6 years, it seems unlikely to ever happen.

Triage: No objections to close, so let's close.
