The GNU libsigsegv library is sometimes used on GNU buildings so I add it to my crazy list of GNU software to manually build. For now, it seems that later on I would have to adjust my GNU m4 macros in order to take into account this new libsigsegv version. Fortunately, later on when I build an updated version of GNU m4 I'll have the option (--with-libsigsegv-prefix) to automatically do that.
The basic building strategy and general assumptions have been detailed on a previous post: Staged Building, so I'll (hopefully) get more straight to the point:
