SIGSEGV in finish () at callNative.S:241 on Synology DS-209

I am getting SIGSEGV running 1.5.4 on Synology DS-209+II

I have complied it myself on the slug. Configure options:

./configure --prefix=/opt --with-classpath-install-dir=/opt --disable-tls

I had to change "lwsync" to "sync" in src/arch.h as otherwise it fails with "invalid instruction" signal.

After that I get a SIGSEGV running any java app.

Backtrace:

root@anaconda:~/wiki.in.a.jar> gdb jamvm

dlopen failed on 'libthread_db.so.1' - libthread_db.so.1: cannot open shared object file: No such file or directory
