This sounds like a similar issue I had on mips64-irix. It wants to run
in 32bit mode, but I have to add compiler flags all over the place to
get all the tools to use 64 bits. You may need to use similar settings.
Most of the flags can be set in mk/build.mk:
# C compiler flags
# Haskell compiler flags, for gcc, and ld
SRC_HC_OPTS+=-optc-mabi=64 -opta-mabi=64 -optl-mabi=64
And the following env vars were needed to be set to help out configure:
export LDFLAGS="-L/usr/freeware/lib64 -mabi=64"
# make sure we use 64bit linker
export LD="/usr/bin/ld -64"
And once this is all built, I need to set some flags in
ghc/rts/package.conf, in order to have the correct flags passed through
for each future Haskell binary you build.

Cool. And send in patches too :)
