expl: Work around inaccurate implementation on NetBSD.
* lib/math.in.h (expl): Test also REPLACE_EXPL.
* m4/expl.m4 (gl_FUNC_EXPL): Add test for a certain accuracy. Set
REPLACE_EXPL.
* m4/math_h.m4 (gl_MATH_H_DEFAULTS): Initialize REPLACE_EXPL.
* modules/math (Makefile.in): Substitute REPLACE_EXPL.
* modules/expl (Depends-on, configure.ac): Test REPLACE_EXPL.
* doc/posix-functions/expl.texi: Mention the NetBSD bug.
