_plyvel.cpython-37m-arm-linux-gnueabihf.so: unexpected reloc type 0x03

Hi,

I have ARM SBM (Odroid-HC1) running Debian Stretch:

# uname -a
Linux odroid-hc1 4.9.0-7-armmp-lpae #1 SMP Debian 4.9.110-1 (2018-07-05) armv7l GNU/Linux

I've tried to install latest plyvel 1.0.5 based on locally built leveldb 1.20. The reason to build with local leveldb is that plyvel 0.9, that would work with Debian Stretch libleveldb-dev, does not seem to support Python 3.7 due to errors like this:

plyvel/_plyvel.cpp: In function ‘void __Pyx_ExceptionSave(PyObject**, PyObject**, PyObject**)’:                                                               plyvel/_plyvel.cpp:18038:21: 
error: ‘PyThreadState {aka struct _ts}’ has no member named ‘exc_type’; did you mean ‘curexc_type’?

So, I've built leveldb 1.20:

# file /root/code/leveldb/leveldb-1.20/out-shared/libleveldb.so.1.20
/root/code/leveldb/leveldb-1.20/out-shared/libleveldb.so.1.20: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, BuildID[sha1]=49e1692ef33cb4e86c0df79864b86a39c343e850, not stripped

And install plyvel like this:

CFLAGS=-I$LEVELDB/include LFLAGS=-L$LEVELDB/out-shared LDFLAGS=-L$LEVELDB/out-shared pip install plyvel

But when I launch application that uses plyvel, I get this:
