Fix conflict between two instantiations of module 'unistd'. * gnulib-tool (func_emit_autoconf_snippet): Substitute ${include_guard_prefix} also in the autoconf snippet. * m4/getopt.m4 (gl_FUNC_GETOPT_POSIX): Don't set GNULIB_UNISTD_H_GETOPT. * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Don't initialize GNULIB_UNISTD_H_GETOPT. * modules/getopt-posix (configure.ac): Set the GNULIB_${gl_include_guard_prefix}_UNISTD_H_GETOPT variable. * modules/getopt-gnu (configure.ac): Likewise. * modules/unistd (Makefile.am): Change the substitution value of GNULIB_UNISTD_H_GETOPT to depend on the include guard prefix. Reported by Simon Josefsson.

Description:
