Re: patch to allow target defined solib search method

["Kris Warkentin" <kewarken@qnx.com>]

Here you go.  I chopped up the long lines and used your formatting for the
ChangeLog.  I also added myself to MAINTAINERS at the bottom of the patch.
Makes sense since I'm the gdb guy at QNX now.  Sorry about the missing tabs
in the ChangeLog.  Outlook doesn't DO tabs...I guess Microsoft doesn't
believe in them. :-P  Would it be better if I just attached text files next
time?

cheers,

Kris

    * solist.h (struct target_so_ops): Add find_and_open_solib().
                   (TARGET_SO_FIND_AND_OPEN_SOLIB): Define.
