libgcc, i386: Add .note.GNU-stack sections to the ms sse/avx sav/res

On Linux, GCC emits .note.GNU-stack sections when compiling code to mark
the code as not needing or needing executable stack, missing section means
unknown.  But assembly files need to be marked manually.  We already
mark various *.S files in libgcc manually, but the
avx_resms64f.o
avx_resms64fx.o
avx_resms64.o
avx_resms64x.o
avx_savms64f.o
avx_savms64.o
sse_resms64f.o
sse_resms64fx.o
sse_resms64.o
sse_resms64x.o
sse_savms64f.o
sse_savms64.o
files aren't marked, so when something links it in, it will require
executable stack.  Nothing in the assembly requires executable stack though.
