My reason is simply that I wanted libstdc++ with debugging symbols on
my machine as my distro (Arch Linux) seems to strip them. It seems
perfectly reasonable to me to want to build only libstdc++ and not the
whole gcc project because building the whole project is a complete
waste of time seeing as I already have the other binaries compiled on
my system from my distribution's packages.

However as Ian very helpfully pointed out, I can only do this if I
have the source code for libstdc++ that matches the version of g++ on
my system. In other words I need to use the same source that my distro
used to build my packages. It turned out my distribution requires me
to modify the script that builds the gnu-libs package to not strip the
debugging symbols, then compile, rebuild the gnu-libs package and then
install this package. I did this and it showed quite nicely how my
distribution builds its package containing libstdc++ .
