Bug#920591: lambda-align2: please make the build reproducible

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that lambda-align2 could not be built reproducibly.

This is because the manpages embed the build-time number of CPUs. For example:

  -number of threads to run concurrently (ignored if a == skew7ext). In range [1..160]. Default: \fI16\fP.
  +number of threads to run concurrently (ignored if a == skew7ext). In range [1..150]. Default: \fI15\fP.

Patch attached.
