commit 8ae2b54ee70891ddb720bf00f8913c3716c1f67f
Author: Waldemar Brodkorb <wbx(a)uclibc-ng.org>
Date: Sat Aug 27 17:45:19 2016 +0200
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(a)synopsys.com>

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.

- help
- Set this to compile all sources at once into an object (IMA).
- This mode of compilation uses alot of memory but may produce
- smaller binaries.

- Note that you need a very recent GCC for this to work, like
- gcc >= 4.3 plus eventually some patches.

- If unsure, keep the default of N.
