test/math/*: unbreak
test/math was not running at all, presume it has bit rotted:
It was trying to run libm-test.c as if it is a binary.
It was looking for libm-test-ulps (file with allowed
errors in lower bits) in arch-specific dirs which do not exist
in uclibc, as a result wrong file (libm-test.inc) was used instead.
Test failure was not showing the error result, user had to
fish it out from some .out files.
I added libm-test-ulps-ARCH files from recent glibc,
this filtered out a lot of false positives.
For example, cosf(M_PI_6l * 4.0) ideally should be -0.5,
we are getting -0.50000005047356477217, and this isn't
a failure (the difference is one lowest bit of mantissa).
"make check UCLIBC_ONLY=1 VERBOSE=1" still fails,
but not as catastrophically as before.
For the record, the failure occurs on the stage where we check
32-bit float functions, these tests fail:
Failure: Test: modf (NaN, &x) == NaN
Failure: Test: ilogb (NaN) == FP_ILOGBNAN plus exceptions allowed
Failure: Test: scalb (2.0, 0.5) == NaN plus invalid exception
Failure: Test: scalb (3.0, -2.5) == NaN plus invalid exception
Failure: Test: scalb (0, NaN) == NaN
Failure: Test: scalb (1, NaN) == NaN
Failure: Test: scalb (0, inf) == NaN plus invalid exception
Failure: Test: scalb (-0, inf) == NaN plus invalid exception
Failure: Test: scalb (1, inf) == inf
Failure: Test: scalb (-1, inf) == -inf
Failure: Test: scalb (inf, -inf) == NaN plus invalid exception
Failure: Test: scalb (-inf, -inf) == NaN plus invalid exception
Failure: Test: scalb (1, NaN) == NaN
Failure: Test: scalb (0, NaN) == NaN
Failure: Test: scalb (inf, NaN) == NaN
Failure: Test: pow (1, NaN) == 1
Failure: Test: pow (1, inf) == 1
Failure: Test: pow (-1, inf) == 1
Failure: Test: pow (1, -inf) == 1
Failure: Test: pow (-1, -inf) == 1
Failure: Test: rint (0.5) == 0.0
Failure: Test: rint (1.5) == 2.0
Failure: Test: rint (2.5) == 2.0
Failure: Test: rint (3.5) == 4.0
Failure: Test: rint (4.5) == 4.0
Failure: Test: rint (-0.5) == -0.0
Failure: Test: rint (-1.5) == -2.0
Failure: Test: rint (-2.5) == -2.0
Failure: Test: rint (-3.5) == -4.0
Failure: Test: rint (-4.5) == -4.0
