Comment (by stigge):

 Turned out that the issue is not necessarily related to cross compiling.

 With:

 autoreconf -fi ; perl boot ; ./configure --target=x86_64-linux-gnu
 --build=x86_64-linux-gnu --host=x86_64-linux-gnu --with-ld=/usr/bin/ld
 --with-gcc=/usr/bin/gcc --with-nm=/usr/bin/nm --enable-unregisterised ;
 make clean ; make

 I get the same error.

 build.mk:

 SRC_HC_OPTS        = -H64m -O0
 GhcStage1HcOpts    = -O
 GhcStage2HcOpts    = -O0
 GhcLibHcOpts       = -O
 SplitObjs          = NO
 HADDOCK_DOCS       = NO
 BUILD_DOCBOOK_HTML = NO
 BUILD_DOCBOOK_PS   = NO
 BUILD_DOCBOOK_PDF  = NO
 INTEGER_LIBRARY = integer-simple
 DYNAMIC_BY_DEFAULT   = NO
 DYNAMIC_GHC_PROGRAMS = NO
 GhcWithNativeCodeGen = NO
 GhcUnregisterised = YES
