Log message:
Unplug assembly implementations of trig functions on x86 platforms
The same change was done by NetBSD some time back as:
Disable x87 implementations of sin, cos, tan.
The x87 hardware uses a bad approximation to pi for argument
reduction, and consequently yields bad answers for inputs near pi or
pi/2.
OK mbuhl@, tested by mbuhl@ and phessler@
