You could try editing the file build/pkgs/giac/spkg-configure.g4: change the line
m4_pushdef([GIAC_MAX_VERSION], [1.7.999])
to something with a larger number, maybe
m4_pushdef([GIAC_MAX_VERSION], [1.9.999])
Then try make distclean and ./configure and see what config.log says about whether it's going to build giac or use the system package.

(The files spkg-configure.m4 for the various packages are used to construct the main configure script, which is what make configure does.)

Edit: my answer is essentially equivalent to the other one. The cited trac ticket makes exactly my proposed change to spkg-configure.m4, after which one should do
make distclean to remove all traces of any previous buildmake configure to rebuild the configure script — this automatically runs ./bootstrap as recommended in the other answer../configure with any relevant argumentsconfig.log to see what it says about building giac. There is a section with the heading "Build status for each package", and the hope is that for giac it will say, "using system package; SPKG will not be installed"make to actually build Sage
