log10: Work around OSF/1 5.1 bug.
* lib/math.in.h (log10): New declaration.
* lib/log10.c: New file.
* m4/log10.m4 (gl_FUNC_LOG10_WORKS): New macro.
(gl_FUNC_LOG10): Invoke it. Set REPLACE_LOG10.
* m4/math_h.m4 (gl_MATH_H): Test whether log10 is declared.
(gl_MATH_H_DEFAULTS): Initialize GNULIB_LOG10, REPLACE_LOG10.
* modules/math (Makefile.am): Substitute GNULIB_LOG10, REPLACE_LOG10.
* modules/log10 (Files): Add lib/log10.c.
(Depends-on): Add math.
(configure.ac): If REPLACE_LOG10 is 1, compile an override.
* tests/test-math-c++.cc: Check the declaration of log10.
* doc/posix-functions/log10.texi: Mention the OSF/1 5.1 problem.
