These were removed from the build for being wrong, but the implementation stayed around. This is confusing, we have the attic for old code, let's delete the unused implementations.

Modified Files:
src/lib/libm/arch/i387: e_acos.S
Log Message:
Drop in a fabs() after the fsqrt().
While it may seem pointless, it the rouding mode is set to round towards
minus infinity then acos(-1) calculates atan2(sqrt(1.0 - 1.0), -1) the subtract
generates -0.0 which sqrt() preserves.
atan2(-0, -1) is -pi, but acos(-1) is expected to be +pi.
This might 'fix' the test failures seen in some environments, but they
are not failing due to an obvously incorrent x87 rounding mode.
