Subject: [PATCH] relocatable-prog-wrapper: Assume strerror() exists.

* modules/relocatable-prog-wrapper (Files): Remove lib/strerror.c,
m4/strerror.m4.
(configure.ac): Don't invoke gl_FUNC_STRERROR_SEPARATE.
* lib/relocwrapper.c: Remove mention of strerror module.
* lib/strerror.c: Assume REPLACE_STRERROR is 1.
* m4/strerror.m4 (gl_FUNC_STRERROR_SEPARATE): Remove macro.
(gl_FUNC_STRERROR): Inline it here. Don't define REPLACE_STRERROR as a
C macro.
