On Linux/x86-64 with 12 cores,
make -j 12 check RUNTESTFLAGS="--target_board 'unix{-m32,}'"
takes 1 hour and 44 minutes while
make -j 12 check
only takes 20 minutes. I got
[hjl@gnu-34 bld]$ ls gcc/testsuite
g++ gcc gfortran objc
[hjl@gnu-34 bld]$
vs
[hjl@gnu-34 bld]$ ls gcc/testsuite
g++ g++2 gcc1 gcc3 gcc5 gfortran gfortran2 objc
g++1 gcc gcc2 gcc4 gcc6 gfortran1 gfortran3 objc1
