Sorry, I've finally got back to looking at this.

+               ".pushsection .rodata.str, \"aMS\", 1\n"        \

According to my gas manual:

| 7.88 `.pushsection NAME [, SUBSECTION] [, "FLAGS"[, @TYPE[,ARGUMENTS]]]'
| ...
|    This directive pushes the current section (and subsection) onto the
| top of the section stack, and then replaces the current section and
| subsection with `name' and `subsection'. The optional `flags', `type'
| and `arguments' are treated the same as in the `.section' (*note
| Section::) directive.
| 
| 7.94 `.section NAME'
| ...
| ELF Version
| ...
|    Note on targets where the `@' character is the start of a comment (eg
| ARM) then another character is used instead.  For example the ARM port
| uses the `%' character.
| 
|    If FLAGS contains the `M' symbol then the TYPE argument must be
| specified as well as an extra argument--ENTSIZE--like this:
| 
|      .section NAME , "FLAGS"M, @TYPE, ENTSIZE
| 
|    Sections with the `M' flag but not `S' flag must contain fixed size
| constants, each ENTSIZE octets long. Sections with both `M' and `S'
| must contain zero terminated strings where each character is ENTSIZE
| bytes long. The linker may remove duplicates within sections with the
| same name, same entity size and same flags.  ENTSIZE must be an
| absolute expression.

It appears that the TYPE argument is missing.  As the GAS manual says
its required, then I think it really ought to be there.  Any comment?
