to answer the last part

as for purpose:
The information is useful as debug information when there are problems
with one of the libraries. (like "Please report your show_config if
you have a problem with xxx")

However, I don't know if any installers check the config info to see
whether packages are fortran compatible, my guess is they don't.
for example, mixing gcc numpy with mkl scipy should cause some errors.
I usually pay enough attention which installers I use, that I never
found out that information. (official binaries versus Gohlke binaries)
