pxe: Send tftp acks after we reach our timeout
While looking at the tftp implementation I noticed that we are not
retransmitting acks if we reach our timeout. Not retransmitting
can be a problem when there is packet loss present in a network.
We do retransmit if the server times out but it is better if
we retransmit ourselves in case we are dealing with a stupid
tftp server that has not noticed it missed a packet from us.

com32, bitops: an "m" constraint takes an object, not a pointer to one
The argument to an "m" constraint is an object, not a pointer to an
object. For a void pointer it needs to be cast to an indirectable
type (like char) and then indirected.

ld: Use ABSOLUTE() when taking differences between relative symbols
binutils 2.21.51.0.6, and possibly other versions, generate the wrong
result when subtracting two section-relative symbols (the final result
ends up having the base of the section incorrectly added to it.) Work
around this by using ABSOLUTE() on the symbols to force the result to
become absolute.
