On Linux/x32, I got

gcc -mx32 -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow
-Werror -g -O2 -static-libstdc++ -static-libgcc -o cxxfilt cxxfilt.o
bucomm.o version.o filemode.o  ../bfd/.libs/libbfd.a
../libiberty/libiberty.a -lz -ldl
/export/gnu/import/git/sources/binutils-gdb/binutils/dwarf.c: In
function ‘read_cie’:
/export/gnu/import/git/sources/binutils-gdb/binutils/dwarf.c:5542:3:
error: format ‘%lx’ expects argument of type ‘long unsigned int’, but
argument 2 has type ‘int’ [-Werror=format=]
   (augmentation_data + augmentation_data_len) - q);
   ^

I checkedin this patch to fix it.
