Auto-generate libc-modules.h
Remove libc-modules.h from the tree and auto-generate it from soversions.i and the list of modules in the built-modules variable defined in Makeconfig. Macros generated have increasing numbered values, with built-modules having lower values starting from 1, following which a separator value LIBS_BEGIN is added and then finally the library names from soversions.i are appended to the list. This allows us to conveniently differentiate between the versioned libraries and other built modules, which is needed in errno.h and netdb.h to decide whether to use an internal symbol or an external one. Verified that generated code remains unchanged on x86_64. * Makeconfig (built-modules): List non-library modules to be built. (module-cppflags): Include libc-modules.h for everything except shlib-versions.v.i. (CPPFLAGS): Use it. (before-compile): Add libc-modules.h. ($(common-objpfx)libc-modules.h, $(common-objpfx)libc-modules.stmp): New targets. (common-generated): Add libc-modules.h and libc-modules.stmp. ($(common-objpfx)Versions.v.i): Depend on libc-modules.h. * include/libc-symbols.h: Don't include libc-modules.h. * include/libc-modules.h: Remove file. * scripts/gen-libc-modules.awk: New script to generate libc-modules.h. * sysdeps/unix/Makefile ($(common-objpfx)sysd-syscalls): Depend on libc-modules.stmp.
