7e8000b396 DWARF: move pessimistic DWARF version checks for imported entities 
A check in dwarf2out_imported_module_or_decl prevents
DW_TAG_imported_module from being emitted as it was introduced in the
DWARFv3 standard. However, this also prevents valid strict DWARFv2
constructs such as DW_TAG_imported_declaration from being emitted in
dwarf2out_imported_module_or_decl_1.

The latter already protects the emission of newer DWARF tags with
appropriate checks, so the one in the former is redundant and
pessimistic.  This function is already called from places like
process_scope_var, which are not protected anyway.

This patch moves the check in dwarf2out_imported_module_or_decl so that
in strict DWARFv2 mode, tags like DW_TAG_imported_declaration are
emitted while DW_TAG_imported_module are not.

gcc/

	* dwarf2out.c (dwarf2out_imported_module_or_decl): Move DWARF
	version check to protect only DW_TAG_imported_module generation.

PR go/77809

    libgo: strip most C macros from runtime.inc
    
    The Go runtime package is picking up C macros from runtime_sysinfo.go
    and then re-exporting them to runtime.inc.  This can cause name
    conflicts.  Change the Makefile so that we only put the macros we need
    into runtime.inc.  These are the constants that are actually defined by
    Go code, not runtime_sysinfo.go.  There are only a few, so we can
    pattern match.
    
    This is an additional hack on runtime.inc.  The long term goal is to
    convert the runtime package to Go and eliminate runtime.inc entirely, so
    a few hacks seem acceptable.
    
    Fixes GCC PR 77809.

d07b0a23a5 Fix failing gcc.target/avr/torture/builtins_error.c 
The compiler defaults to thin LTO objects if built with linker plugin
support, and in that case, the error expected by the testcase appears 
only at link time, if at all. Forcing fat LTO object file creation 
generates the error consistently at compile time, as expected.
