tools/testbuild.sh: update makefunc to hardcode make/extra flags options and redirection

Aim to let makefunc caller just pass in the target. So update makefunc to hardcode make/extra
flags options and redirection, meanwhile avoid the case in which makefunc would remove the quotes
for EXTRAFLAGS. Note that JOPTIONS should also hardcode once parallel build break finally fixed.
