Intermittent SSL linking failures on Mac OS X

[cr]

Depending on a certain celestial constellation and the weather, builds on Mac are failing with a SSL-related linker error. Sometimes, the build goes fine for hours, then, some other time, the build fails between one and five times in a row – until it magically succeeds – with:

error: linking with `cc` failed: exit code: 1
