It looks to me like your spkg-install for giac has custom modifications. From
the log

Configuring giac...
configure: WARNING: you should use --build, --host, --target
The line that makes me curious is "sed: can't read input_parser.cc: No such
file or directory”
and you are failing on that file. I cannot find a sed line in spkg-install on
github for sage-8.0
(or the current beta) so this is very curious.
