function_reordering_plugin.c includes <elf.h> which is not available
on non-ELF platforms building a cross-compiler. This patch checks for
<elf.h> before including it. Otherwise, it redefines the macros used.
This is safe because the macros will not change.

For context, this linker plugin itself is only available in the google
4_6 branch and I will port it to other branches and make it available
for review for trunk soon.

	* function_reordering_plugin.c: Check for presence of elf.h.
	Otherwise, redefine the elf macros used.

Ok to commit?

Thanks,
-Sri.
