iBFT (i.e. scanned for and identified by signature, rather than being
at a fixed address), but it works for now.

algorithms; we only need the pubkey check disabled (and only because
pubkey algorithms are not yet integrated into the crypto_algorithm
subsystem).

Experimentation reveals that gcc ignores -mrtd for the implicit
arithmetic functions (e.g. __udivdi3), but not for the implicit
memcpy() and memset() functions.  Mark the implicit arithmetic
functions with __attribute__((cdecl)) to compensate for this.

(Note: we cannot mark with with __cdecl, because we define __cdecl to
incorporate regparm(0) as well.)

really ugly hack at present, but that doesn't hugely matter since I'm
aiming to change the interface to iSCSI devices anyway within the next
week.
