Michael Brown 1b99ba2a93 [build] Work around stray sections introduced by some binutils versions
Some versions of GNU ld (observed with binutils 2.36 on Arch Linux)
introduce a .note.gnu.property section marked as loadable at a high
address and with non-empty contents.  This adds approximately 128MB of
garbage to the BIOS .usb disk images.

Fix by using a custom linker script for the prefix-only binaries such
as the USB disk partition table and MBR, in order to allow unwanted
sections to be explicitly discarded.
