I just unpacked all of the spkg files and did "grep SAGE64 -R ." from
SAGE_ROOT/spkg/standard, and got lots of hits. Here are a few examples:

if [ "$SAGE64" = "yes" ]; then
echo "64 bit build"
CFLAGS="-O2 -g -fPIC -m64 "; export CFLAGS
LDFLAGS="-m64"; export LDFLAGS

echo "Building a 64-bit version of ECL"
CFLAGS="$CFLAGS $CFLAG64"
CXXFLAGS="$CXXFLAGS $CXXFLAG64"
LDFLAGS="$LDFLAGS $CFLAG64"
fi

if [ "x`uname -sm`" = "xSunOS i86pc" ] && [ "x$SAGE64" = xyes ] ; then
# Need to add --with-dffi=no to disable assembly code on OpenSolaris
x64.
# and Solaris 10 on x64.
# The option is only given if all the following are true
# 1) Solaris, Solaris Express or OpenSolaris (SunOS)
# 2) Intel or AMD CPU
# 3) 64-bit build
./configure --prefix="$SAGE_LOCAL" --with-dffi=no
else
./configure --prefix="$SAGE_LOCAL"
