This is a cleanup patch removing the obsolete LINUX_DEFAULT_ELF
definition.

There were two places where the preprocessor symbol was being
used as a boolean flag for tweaking LINK_SPEC to use
/lib/elf/ld-linux.so.1.

Both these cases were unreachable because in both cases
LINUX_DEFAULT_ELF was unconditionally defined at the top of
the header file.


2003-09-03  Bernardo Innocenti  <bernie@develer.com>

	* config.gcc (m68k-*-linux*): Remove definition of LINUX_DEFAULT_ELF.
	* config/i370/linux.h (LINUX_DEFAULT_ELF): Remove unconditional
	definition and code blocks compiled when not defined.
	* config/i386/linux.h (LINUX_DEFAULT_ELF): Likewise.
	* config/i386/linux64.h (LINUX_DEFAULT_ELF): Likewise.
	* config/sparc/linux.h: (LINUX_DEFAULT_ELF): Likewise.
	* config/sparc/linux64.h: (LINUX_DEFAULT_ELF): Likewise.
