  The r17-2455-gf8c277ed801ba6 enabled test_custom unconditionally for both
double and float, however all-combination test shows that double remains
unstable.

libstdc++-v3/ChangeLog:

	* testsuite/26_numerics/random/piecewise_linear_distribution/operators/serialize2.cc:
	Enable test_customd<double> for __x86_64__.
---
I must have confused fix for float with fix for all of them.
However, as the r17-2455-gf8c277 should not affect results for double
(RealType is same as CalcType), this should be expected.

Pushed to trunk.
