[lfs-dev] gcc 5.1.0 test suite time out errors.

I'm building a pure 64 bit instance of the current dev version of LFS, and
in chapter 6 it calls the tests for gcc critical - and I'm getting a lot of
unexpected failures in the gcc test suite - I've pasted an abstract down
below.

The failures are all time outs around the cilk functionality. The
virtualbox vm I'm building on is running a clean install of Ubuntu 15.04
server (no ui), with 1G ram, one cpu ( it's an Ivy Bridge Intel i3320m)

Is this OK, or am I wasting my time going forward from here?
