undefined references since newlib-3.2.0

Hello everybody,



Since newlib-3.2.0, I get this error when linking one of my projects:

The project builds just fine with newlib versions up to 3.1.0



newlib was configured like this:



/m/a/tmp/builds/crossgcc/src/newlib-3.2.0/configure --target=m68k-unknown-elf --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --prefix=/m/a/local/crossgcc/m68k-unknown-elf/nanoLibraries --enable-lite-exit --enable-newlib-nano-malloc --enable-newlib-nano-formatted-io --enable-newlib-reent-small --enable-newlib-retargetable-locking --enable-newlib-global-atexit --enable-newlib-global-stdio-streams --disable-newlib-supplied-syscalls --disable-newlib-fvwrite-in-streamio --disable-newlib-fseek-optimization --disable-newlib-wide-orient --disable-newlib-unbuf-stream-opt --disable-nls



Any suggestions?
