and rule for it conditional on termio.h not already being in
sysdep_headers.
* rpm/Makefile (install-others) [libc.so-version]: Get libc.so from
$(libdir), only the versioned named from $(slibdir).
(instfiles): New variable.
(glibc-$(version).$(config).rpm): New target. Run rpm -bb.
* rpm/rpmrc: New file. A third of the options controlling rpm can
only be given here (another third is on the command line, and a third
cannot be specified in any way shape or form).
