[PATCH] D13637: ELF2: Fix BSD's __progname symbol issue.

BSD's DSO files have undefined symbol "__progname" which is defined in crt1.o.
On that system, both user programs and system shared libraries depend on each
other. We need to put symbols defined by user programs which are referenced
by shared libraries to user program's .dynsym.
