Changelog:

  - nall/GNUmakefile: fixed findstring parameter arguments [Screwtape]
  - nall/Windows: always include -mthreads -lpthread for all
    applications
  - nall/memory: code restructuring

I really wanted to work on the new PPU today, but I thought I'd spend a
few minutes making some minor improvements to nall::memory, that was
five and a half hours ago. Now I have a 67KiB diff of changes. Sigh.
