Remove Wundef warnings for specification macros
This patch adds a file posix-conf-vars.list that is used to generate macros to determine if a macro is defined as set, unset or not defined. gen-posix-conf-vars.awk processes this file and generates a header (posix-conf-vars-def.h) with these macros. A new header posix-conf-vars.h includes this generated header and defines accessor macros for the generated macros. Tested on x86_64. * posix/Makefile (before-compile): Add posix-conf-vars-def.h. ($(objpfx)posix-conf-vars-def.h): New target. * posix/posix-conf-vars.list: New file. * posix/posix-conf-vars.h: New file. * posix/confstr.c: Include posix-conf-vars.h. (confstr): Use CONF_IS_* macros. * posix/posix-envs.def: Include posix-conf-vars.h. Use CONF_IS_* macros. * scripts/gen-posix-conf-vars.awk: New file.
