"-mg" didn't work.  It looks like the format of the TARGET_SWITCHES
macro needs updating in vax.h.  This is the current definition:

#define TARGET_SWITCHES  \
  { {"unix", 1},  \
    {"gnu", -1},  \
    {"vaxc-alignment", 2}, \
    {"g", 4}, \
    {"g-float", 4}, \
    {"d", -4},  \
    {"d-float", -4}, \
    { "", TARGET_DEFAULT}}

Other machines have a third comment field for each switch.
