This is the LTO issue with -fpic/-fpie on SPARC/Linux.  When the special GOT 
helper function is generated, the compiler invokes:

	  make_decl_one_only (decl, DECL_ASSEMBLER_NAME (decl));

on it, which sets the TREE_PUBLIC flag as expected.  The problem is that, in 
LTO mode, DECL_ASSEMBLER_NAME (decl) depends on TREE_PUBLIC being set or not.

Tested on SPARC/Linux, applied to all active branches.

	PR target/52717
	* config/sparc/sparc.c (sparc_file_end): Set TREE_PUBLIC explicitly on
	the DECL generated for the special GOT helper.
