* libio/Makefile (routines): Add fwprintf. PowerPC has own version of w_sqrt.c and w_sqrtf.c. * math/w_sqrt.c: Moved to ... * sysdeps/generic/w_sqrt.c: ... here. * math/w_sqrtf.c: Moved to ... * sysdeps/generic/w_sqrtf.c: ... here. * Make-dist (generic-dirs): New variable. (try-sysdeps, +sysdep-names): Use it. * extra-lib.mk (all-$(lib)-routines): New variable. Use it instead of $(lib)-routines. * elf/Makefile (distribute): Add dl-cache.h. * db2/Makefile (distribute): Add all new files. * iconvdata/Makefile (distribute): Don't distribute CVS directory. * math/Makefile (distribute): Remove machine/endian.h, add math_ldbl.h. * stdio-common/Makefile (distribute): Add _itowa.h. * sysdeps/generic/Dist: Remove make_siglist.c, add siglist.h. * sysdeps/gnu/Dist: Add eval.c * sysdeps/gnu/Makefile (libdl-sysdep_routines) [$(subdir) = dlfcn]: Add to this instead of libdl-routines. * sysdeps/ieee754/ldbl-128/Dist: New file. * sysdeps/mach/hurd/Dist: Add siglist.h * sysdeps/unix/sysv/linux/Dist: Add kernel-features.h.
