For anyone building on Debian testing or similar and getting linker failures, there is currently a workaround in progress by Ben Gamari that can be used.
It is based on first applying D2672, D2673, and D2674 and then configuring with
./configure \ CONF_CC_OPTS_STAGE2=-fno-PIE \ CONF_GCC_LINKER_OPTS_STAGE2=-no-pie \ CONF_LD_LINKER_OPTS_STAGE2=-no-pie \ CONF_CC_OPTS_STAGE0=-no-pie \ CONF_GCC_LINKER_OPTS_STAGE0=-no-pie \ CONF_LD_LINKER_OPTS_STAGE0=-no-pie \ CONF_HC_OPTS_STAGE0=-optl=-no-pie
Unfortunately, that is not sufficient. With the three patchs you listed and the configure options above, the resulting GHC still fails to build the 'magic' due to something going wrong with hsc2hs: Configuring magic-1.1...

Preprocessing library magic-1.1... /usr/bin/ld: dist/build/Magic/Data_hsc_make.o: relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC /usr/bin/ld: final link failed: Nonrepresentable section on output collect2: error: ld returned 1 exit status linking dist/build/Magic/Data_hsc_make.o failed (exit code 1) command was: /usr/bin/gcc dist/build/Magic/Data_hsc_make.o dist/build/Magic/Data_hsc_utils.o -o dist/build/Magic/Data_hsc_make -fno-PIE -fno-stack-protector -lmagic -L/usr/lib/ghc-8.0/lib/base-4.9.0.0 -Wl,-R,/usr/lib/ghc-8.0/lib/base-4.9.0.0 -L/usr/lib/ghc-8.0/lib/integer-gmp-1.0.0.1 -Wl,-R,/usr/lib/ghc-8.0/lib/integer-gmp-1.0.0.1 -lgmp -L/usr/lib/ghc-8.0/lib/ghc-prim-0.5.0.0 -Wl,-R,/usr/lib/ghc-8.0/lib/ghc-prim-0.5.0.0 -L/usr/lib/ghc-8.0/lib/rts -Wl,-R,/usr/lib/ghc-8.0/lib/rts -lm -lrt -ldl -lffi Erik -- ---------------------------------------------------------------------- Erik de Castro Lopo http://www.mega-nerd.com/
