* sunrpc/Makefile (install-lib): Variable removed. (rpcsvc-objs): Variable removed. (extra-objs): Don't include $(rpcsvc-objs). (extra-libs): New variable, contains librpcsvc. (librpcsvc-routines): New variable. (librpcsvc-inhibit-o): New variable, contains .so. (omit-deps): Set this to $(librpcsvc-routines). ($(objpfx)rpcgen): Don't use $(libc.a). (lib, $(objpfx)librpcsvc.a): Targets removed. * o-iterator.mk, extra-lib.mk: New files. * Makerules (o-iterator): New variable. [extra-libs]: Include extra-lib.mk to generate rules for each word of $(extra-libs). * Makefile (distribute): Add extra-lib.mk, o-iterator.mk. (IMPLICIT_ONE, *_MAX_10_EXP_LOG): Macros removed; no longer needed. * stdio/fpioconst.c, stdio/fpioconst.h: Don't use LDBL_MAX_10_EXP_LOG; LAST_POW10 defines the maximal available exponent.
