I have always been confused about these pieces. The "Prerequisites"
say we need these libs and then also say "but NOT THOSE LIBS use these
over here instead".  It also says "don't be silly" which isn't really
helpful.

So there seems to be things here :

      ftp://gcc.gnu.org/pub/gcc/infrastructure/

However those libs *should* be the real libs from the real source sites
but they are not. Actual libgmp is at version 6.1.2 and the bugfixes and
updates are being done in the libgmp project for a reason. It is trivial
to get the sources, build them, install into a very defacto standard
path like /usr/local.   For that matter one may simply extract them into
the gcc source path and continue that way. I have had great success this
way and it does not at all seem "silly". It seems correct to have the
real correct sources from those projects.
