Try

* m68k-rtems-gcc --help.

* info gcc 
Then follow 
a) Invoking GCC->Directory Options
b) Invoking GCC->Overall Options

* OAR's online-version of gcc.info:

Here are two issues with this line:
a) -B/usr/local/rtems/lz120_ROM/lib/
The / at the end is essential.

b) -specs bsp_specs or -specs=bsp_specs
-specs gives the name of the file searched in -B<path>/ not the path
to bsp_specs

Yes, these are caused by the issues above.
