Support dynamic assignment of DSBT_INDEX
For DSBT targets (C6X only at this point), we'd like to support the case
where the user did not specify --dsbt-index at link time when building a
shared library. The dynamic linker can still assign an index at runtime
and fix up the DSBT_INDEX relocs, at the cost of startup time and memory
space.
