In order to align the entry points for the various stages
on x86 to _start one needs to rename the reset_vector symbol.
The section is the same; it's just a symbol change.

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

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.

The x86 bootblock linking is a mess. The bootblock is treated in
a very special manner, and never received the update to link-time
garbage collection.
On newer x86 platforms, the boot media is no longer memory-mapped.
That means we need to do a lot more setup in the bootblock. ROMCC is
unsuitable for this task, and walkcbfs only works on memory-mapped
CBFS. We need to revise the x86 bootflow for this new case.
The approach this patch series takes is to perform CAR setup in the
bootblock, and load the following stage (either romstage or verstage)
from the boot media. This approach is not new, but has been done on
our ARM ports for years.
Since we will be adding .c files to the bootblock, it is prudent to
use link-time garbage collection. This is also consistent to how we
do things on other architectures. Unification FTW!

It never made sense to have bootblock_* in init, but
pirq_routing.c in boot, and some ld scripts on the main
level while others live in subdirectories.
This patch flattens the directory hierarchy and makes
x86 more similar to the other architectures.
