 As another point of reference: it didn't occur for ruby-2.4.0.

 ruby has a bunch of optional dependencies, so yes indeed it only occurs for
some exotic combination of these dependencies.

 So I checked the source of the Sourcery toolchain and it does NOT have the
patch of bug 20006 applied, even though it was released in binutils 2.26.1, 4
months before the Sourcery release...

 So, we could try to find out which exact combination of packages triggers this
issue, but is that worth it for something that happens twice in five months...
