/* ldindr.c
Handle indirect symbols.
BFD supplies symbols to be indirected with the BFD_INDIRECT bit
set. Whenever the linker gets one of these, it calls add_indirect
with the symbol. We create an entry into the ldsym hash table as if it
were a normal symbol, but with the SYM_INDIRECT bit set in the
flags.
When it comes time to tie up the symbols at a later date, the flag
will be seen and a call made to do the right thing (tm)
