I don't know at what point this changed, but with gcc 11.2.0 and
binutils 2.38, if we don't restrict what sections are output to the raw
binary, the ".note.gnu.property" section in the object file will be
written into the first 48 bytes of the EDID, rendering it unusable.

To fix this, limit the binary output to the ".data" section.
