Don't expose AC_{COMPILE,LINK}_IFELSE internals in documentation.

* doc/autoconf.texi (Runtime) <AC_LINK_IFELSE>: Suggest to use
`conftest$EXEEXT' rather than `conftest$ac_exeext' to acces the
just-linked program file.
(Runtime) <AC_COMPILE_IFELSE>: Suggest to use `conftest.$OBJEXT'
rather than `conftest.$ac_object' to access the just-compiled
object file.  Also, refer to the object file as "just-compiled"
rather than "just-linked".
