686b1cdfdc 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.

1ecae1fc23 Enable building libgcc with CET options. 
Enable building libgcc with CET options by default on Linux/x86 if
binutils supports CET v2.0.  It can be disabled with --disable-cet.
It is an error to configure GCC with --enable-cet if bintuiils
doesn't support CET v2.0.

ENDBR instruction is added to __morestack_large_model since it is
called indirectly.
