remove DOMULTI support
A single test with targeting ARM showed that this feature seems bit rotted. Remove DOMULTI and simplify Makefiles.
commit f9d8ce5ae0ed1e1a639ddc9b2b64726eab569c66 Author: Eugeniy Paltsev Eugeniy.Paltsev@synopsys.com Date: Tue Aug 23 12:41:18 2016 +0300
ARC: Fix max ULP for cosine test
Max ULP for "cos (M_PI_6l * 2.0) == 0.5" in "test-double" sub-test is set to "0" for ARC. It causes "test-double" test failure.
I realized that this sub-test on ARM gets completely same results. But it doesn't fails on ARM because max ULP is set to "1" for ARM.
I am wondering, if it was done for any special reason?
Otherwise, set max ULP for "cos (M_PI_6l * 2.0) == 0.5" test to "1" instead of "0" for ARC.
