* configure.in (sparc-sun-solaris2*): Don't use /usr/bin/which on
Solaris when testing for the /usr/ucb/cc compiler; it has incorrect
semantics. Use the shell built-in "type" command instead.
From-SVN: r45687
* config.gcc (s390-*-linux-*, s390x-*-linux*): Switch to
new-style tm_file specification. 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.
