Comment (by bgamari):

 So I spent quite a while today working through building a tree with the
 new compiler. It turns out there are a number of build system issues which
 get in the way of this which I've fixed in Phab:D2672, Phab:D2673, and
 Phab:D2674. With these patches you can simply configure with,
 {{{
 $ ./configure \
     CONF_GCC_LINKER_OPTS_STAGE0=-no-pie \
     CONF_LD_LINKER_OPTS_STAGE0=-no-pie \
     CONF_HC_OPTS_STAGE0=-optl=-no-pie
 }}}
 and build as usual.

 It's not entirely clear here why the Haskell compiler options shouldn't
 just include `CONF_LD_LINKER_OPTS_*` with the appropriate prefix but I
 didn't want to change that today so instead I just passed
 `CONF_HC_OPTS_STAGE0` explicitly.

 Note that it is only necessary to pass `-no-pie` to the stage0 link; the
 later stages should build with `-fPIC` as this is the new compiler's
 default.
