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.

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