Hi,
I also saw this on arm-none-linux-gnueabi and arm-none-eabi with below
error messages:

/../opcodes  -g -O2  -o run \
 run.o libsim.a ../../bfd/libbfd.a ../../opcodes/libopcodes.a
../../libiberty/libiberty.a -lz -lnsl
../../bfd/libbfd.a(plugin.o): In function `try_load_plugin':
....../src/binutils-gdb/bfd/plugin.c:168: undefined reference to `dlopen'
....../src/binutils-gdb/bfd/plugin.c:175: undefined reference to `dlsym'
....../src/binutils-gdb/bfd/plugin.c:171: undefined reference to `dlerror'
Could we add some check for dlopen/dlsym/dlerror in sim configure
script to disable it by default?

Thanks,
bin
