S/390 config file changes

This patch switches the s390 and s390x targets to use new-style tm_file lists,
as suggested by Joseph Myers. It also adds the necessary specifications for
tm_p_file, md_file, and out_file to make the s390x targets actually work.
OK to commit the config changes to mainline?

2001-08-11 Ulrich Weigand <uweigand@de.ibm.com>:
* config.gcc (s390-*-linux-*, s390x-*-linux*): Switch to
new-style tm_file specification. Add xmake_file fragments.
Specify correct tm_p_file, md_file, and out_file for s390x.
* config/s390/linux.h, linux64.h: Don't include other target
macro header files. Now handled via tm_file.
* config/s390/linux.h, s390.h: (IEEE_FLOAT, TARGET_IEEE_FLOAT,
TARGET_IBM_FLOAT): Move from linux.h to s390.h to ensure they
are defined before use.
