arch/x86/bootblock: Link in object files selected with bootblock-y
As part of preparing for systems with non-memory-mapped media, we want
to be able to call into C code. This change allows us to link C code
directly into the bootblock. The steps of going from bootblock main()
to CAR setup to C code will be implemented in subsequent patches.
Note that a few files selected with bootblock-y will now be compiled
for the bootblock as well, but since we enabled garbage collection,
they will not be included in the final binary.
