sqrtl: Bypass broken implementation in OpenBSD 5.1/SPARC. * lib/math.in.h (sqrtl): Replace it if REPLACE_SQRTL is 1. * m4/sqrtl.m4 (gl_FUNC_SQRTL_WORKS): New macro. (gl_FUNC_SQRTL): Invoke it. Set REPLACE_SQRTL to 1 if sqrtl() produces too big rounding errors. * m4/math_h.m4 (gl_MATH_H_DEFAULTS): Initialize REPLACE_SQRTL. * modules/math (Makefile.am): Substitute REPLACE_SQRTL. * modules/sqrtl (configure.ac): Consider REPLACE_SQRTL. (Depends-on): Update conditions. * tests/test-sqrtl.c (my_ldexpl): New function. (main): Add test of a particular value. * doc/posix-functions/sqrtl.texi: Mention the OpenBSD 5.1/SPARC bug.
