Per binutils/docs/as/Section.html, COFF assembly, which is what MinGW uses, does not
allow @type/%type, which is an ELF-only thing. As a result, trying to assemble the
recently modified ctor.S with MinGW produces the error:
Error: junk at end of line, first unrecognized character is `,'
Fix this by making sure ELF-specifics are only added within ELF-guarded sections.
