And then there's the next build problem:

  [BUILD] bin/myri10ge.o
drivers/net/myri10ge.c: In function 'myri10ge_command':
drivers/net/myri10ge.c:308:3: error: dereferencing type-punned pointer will 
break strict-aliasing rules [-Werror=strict-aliasing]
drivers/net/myri10ge.c:310:2: error: dereferencing type-punned pointer will 
break strict-aliasing rules [-Werror=strict-aliasing]
cc1: all warnings being treated as errors
make[7]: *** [bin/myri10ge.o] Error 1
make[7]: Leaving directory 
`/root/xen/xen-4.2.0-rc2/tools/firmware/etherboot/ipxe/src'
