Here are the solutions:
host_multi.c:(.text+0xfc): undefined reference to `e_load_group'

GCC needed to link to both e-hal and e-loader in the newer SDK version. So in build_multi.sh add -le-loader to the gcc line as such:
COMMAND="gcc ${DEFINE_FLAG} src/host_multi.c -o Debug/host_multi.elf -I ${EINCS} -L ${ELIBS} -le-hal -le-loader"
host_multi.c:(.text+0xea): undefined reference to `e_reset_core'

e_reset_core was replaced with e_reset_group in the latest SDK
So replace the loop of e_reset_core calls with one call to e_reset_group in host_multi.c:
e_reset_group(&dev);
//for ( i=0 ; i < group_rows_num; i++ ) {
// for ( j=0 ; j < group_cols_num ; j++ ) {
// e_reset_core(&dev, i, j);
// }
//}
