Bug#891547: cairo: test runs into buildd timeout without fpu

[Adrian Bunk]

Source: cairo
Version: 1.15.10-2
Severity: serious

On the fpu-less armel port the build ran into the 150 minute timeout
during the tests.

With an fpu-less buildd the mips build ran into the 360 minute timeout
during the tests.

These timeouts are time without anything output during the build.

On the abel porterbox (that is the same hardware as the armel/armhf
buildds) I got a successful armel build after 4h 18m.

This is three times the durtion of the successful armhf build,
which wouldn't be surprising if plenty of fp code is run.

The ia64 failure is likely a real problem somewhere,
Jason is currently debugging that.

Possible solutions:
1. get some output during the tests (disable the output redirection), or
2. don't run the tests on the armel and mips architectures
   (mipsel and mips64el are fine)
