manu d77ec799a5 Support Darwin static binaries (I should say: support the only Darwin 
static binary: otool). Dynamic binaires have a pointer to the Mach-O
header on the top of the stack, static binaries don't have this, and
having it produced a crash.

One bugfix: the EXEC_MACHO code assumes that entry = NULL means that
the entry point has not been found in the load commands seen so far.
Therefore we need to initialized entry to NULL if we want a static binary
to discover it. (dynamic binaries were forced to iscover it because when
the intepreter load command is found, entry is updated whatever its
value was before).

One hack: Both COMPAT_MACH and COMPAT_DARWIN are willing to run Mach-O
binaries. COMPAT_MACH fails for dynamic binaries because it cannot find
the interpreter in /emul/mach. For static binaires, it will accept them
(and for Darwin static binaries, this will cause a failure). Until we
rite a test for matchinf Darwin static binaries, just swap the order of
COMPAT_MACH and COMPAT_DARWIN in the exec switch so that COMPAT_DARWIN
is tried first (this will have the advantage of speeding up program
startup). EXECSW_PRIO_{FIRST_LAST} does not seem to work...
