i've run into this too, versions published after 2017-06
seems to use .gz and .xz (that includes gcc-5.5.0, gcc-6.4.0,
gcc-7.2.0, gcc-7.3.0 and gcc-8.1.0)

may be the url could be a list and if the first one fails
with 404 then retry the second. (e.g. gmp has some versions
without .gz and others without .xz tarball so there is no
single pattern that always works)
