Comment (by erikd):

 The test `( cd testsuite && make TEST=ado001 stage=1 )` passes on arm64.

 Running the whole test suite like that and I get a number of failures due
 to the fact that its only the stage1 compiler (ie all ghci, TH and
 annoations tests), but I also get this one failing:

 {{{
 make test stage=1 TEST="T5435_v_asm"
 }}}

 but that passes on x86_64. Sure enough, looking at `rts/Linker.c` there is
 no `aarch64_
 HOST_ARCH` section.
