Compile with -fexcess-precision=standard for i[3456]86 when we can

Browse source 
* configure.ac: when -fexcess-precision=standard is available and we're
building for i[3456]86, use it.  This fixes floating point precision
problems caused by x87 (80-bit) floating point, and detected by
numbers.test.
