When I try to build talloc on a QNX 6.4.1 system, it fails as follows:

 gcc -shared  -o libtalloc.so.1.4.0 ./talloc.o  replace.o snprintf.o getpass.o strptime.o timegm.o   libtalloc.so.1
 gcc: libtalloc.so.1: No such file or directory

The problem is that SONAMEFLAG is empty, so gcc misinterprets "libtalloc.so.1" as a file name instead of as the SO name.

The linker on QNX accepts both -h and -soname flags to specify the SO name, so this problem can be fixed by setting SONAMEFLAG to "-Wl,-h,", "-Wl,-soname,", or "-Wl,-soname=".
