[Bug libstdc++/33612] make check -jN should fully use N cores

[bkoz at gcc dot gnu dot org]

Jason has suggested a good idea to fix this without messing about with test
harness issues.

We can just split

make check 

up into 

make check1
make check2
make check3
make check4
make check5
make check6
...

where the old "make check" is equivalent to make check[1-n] in terms of test
coverage. This will allow 

make -j4 check

to run

make check1
make check2
make check3
make check4

all at the same time.

This should speed things up greatly on current hardware.

Seems simple enough: I feel a bit silly for not having thought of this before.
This is of relatively high priority given the time requirement for libstdc++
testing.
