VxWorks config fixes for shared objects
This strengthens the VxWorks configuration files for the support
of shared objects, which encompasses a VxWorks specific "non-static"
mode for RTPs (in addition to -static and -shared).

gcc/
* config/vx-common.h: Define REAL_LIBGCC_SPEC since the
'-non-static' option is not standard.
* config/vxworks.h (VXWORKS_LIBGCC_SPEC): Implement the LIBGCC_SPEC
since REAL_LIBGCC_SPEC is used now.
(STARTFILE_PREFIX_SPEC): Use the PIC VSB when building shared libraries
or non-static binaries.
