[$] Linker limitations on 32-bit architectures

Before a program can be run, it needs to be built. It's a well-known factthat modern software, in general, consumes more runtime resources thanbefore, sometimes to the point offorcing users to upgrade their computers. But it also consumes more resourcesat build time, forcing operators of the distributions' build farms to investin new hardware, with faster CPUs and more memory. For32-bit architectures, however, there exists a fundamental limit on the amountof virtual memory, which is never going to disappear. That is leading tosome problems for distributions trying to build packages for those architectures.
