[PATCH] ARC: Fix max ULP for cosine test

[PATCH] ARC: Fix max ULP for cosine test

[Eugeniy Paltsev]

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.

Thanks applied and pushed. Normally I autogenerate the ULPS files
with tst-float -u .. and then merging with the perl script.

best regards
