My solution certainly isn't pretty:
!
! Ensure when in crossbuild mode that generate_options is still native. The
! IA64 image is still built in the [.X86_64] directory so we don't have to change
! references to $(ARD)generate_options.exe in other dependency rules.
! Macros:
!    AR_MODE    XBUILD or NATIVE
!    ARD              Sub-directory for architecture-specific targets (e.g. [.IA64]).
!
.if $(AR_MODE) .eq XBUILD
[-.X86_64]generate_options.exe : [.X86_64]generate_options.obj
   link_image = f$trnlnm("IA64_LINK","LNM$PROCESS")
   deassign IA64_LINK                           ! undo X86_TOOLS re-definition
   link /exec=[-.X86_64]generate_options.exe [-.X86_64]generate_options.obj
   define IA64_LINK 'link_image'           ! restore X86_TOOL re-definition

[-.X86_64]generate_options.obj : generate_options.c
   go_cc = f$extract(1,f$length(cc)-1,cc)	! Change XCC to CC
   go_cc $(cflags)/pointer_size=short generate_options.c /object=[-.X86_64]generate_options.obj

.else
$(ARD)generate_options.exe : $(ARD)generate_options.obj
   link /exec=$(ARD)generate_options.exe $(ARD)generate_options.obj

$(ARD)generate_options.obj : generate_options.c
   cc $(cflags)/pointer_size=short generate_options.c /object=$(ARD)generate_options.obj

.endif


It would be even worse if I had to worry about 64-bit being an option.
