This is possibly related to ASLR -- the configure test passes when compiled
with -fno-pie, however using that option to compile the runtime results in:

../Mmake.common:130: warning: undefined variable 'DESTDIR'
../scripts/mgnuc --grade asm_fast.gc     --c-debug --no-ansi   --
 -fPIC -DMR_PIC \
-c mercury_builtin_types.c -o mercury_builtin_types.pic_o
mercury_hand_compare_body.h:41:Missing operand value assumed absolute 0.
mercury_hand_compare_body.h:41:junk `[.-0b]' after expression
mercury_hand_compare_body.h:41:Missing operand value assumed absolute 0.
...

Cheers,
Julien.
