The command line for the symbols looks wrong. I have been working on
those command today and have some unreleased documentation that may help:
 
https://ftp.rtems.org/pub/rtems/people/chrisj/docs/user/tools/index.html#rtems-symbols
 
I suggest you:
 
- remove the '-e' flags if you are not embedding the symbol table in the
base kernel image.
 
- remove 'arm-rtems4.11-gcc' from '-c' option as this is the compiler
name and not a cflag.
 
- if you are using a 4.12 build of rtems-syms with 4.11 you may need to
provide a suitable executable prefix via the '-E' option.
 
I hope this helps.
