You have at least two choices. For both, start by downloading (http://www.sagemath.org/download-source.html) and unpacking sage-8.0.tar.gz wherever you plan to build it.
Choice 1: install git-trac-config: see http://doc.sagemath.org/html/en/developer/git_trac.html#installing-the-git-trac-command. (So run "git clone https://github.com/sagemath/git-trac-command.git"; in some suitable directory, separate from the Sage installation, and then run "source git-trac-command/enable.sh". Then cd into the Sage-8.0 directory. Run "git trac config". Then run "git trac checkout 23898". Also download the tarball for gcc-7.2 from that ticket and put it in sage-8.0/upstream. Then run "make". Choice 2: skip the git business and just make the changes directly: edit the file "sage-8.0/build/pkgs/gcc/package-version.txt" to say "7.2.0". Also download a gzipped tarball for gcc-7.2 (for example from ftp://ftp.fu-berlin.de/unix/languages/gcc/releases/gcc-7.2.0/gcc-7.2.0.tar.gz) and put it in sage-8.0/upstream. Then run "./sage --package fix-checksum gcc". Then run "make".
