fails to build with hardening flags enabled (relocation R_X86_64_32 against `stg_CHARLIKE_closure'...)

Building HEAD on Debian wheezy with the Debian packaging setup fails:

configure: Building in-tree ghc-pwd
/usr/bin/ld: utils/ghc-pwd/dist-boot/Main.o: relocation R_X86_64_32 against `stg_CHARLIKE_closure' can not be used when making a shared object; recompile with -fPIC
utils/ghc-pwd/dist-boot/Main.o: could not read symbols: Bad value
collect2: error: ld returned 1 exit status
configure: error: Building ghc-pwd failed

http://deb.haskell.org/dailies/2014-04-16/ghc_7.9.20140416-0.daily_amd64.build

This is possibly related to the Hardening flags added by Debian:

~ $ dpkg-buildflags --get LDFLAGS
-Wl,-z,relro
~ $ dpkg-buildflags --get CFLAGS
-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security

Other related bug might be #3668 (closed) and https://bugs.debian.org/712228

I’ll disable the hardening flags and see if it helps. The error first occurred 2014-03-27.
