Before this patch, building talloc on darwin (OS X 10.8.5) results in:
gcc -dynamiclib -Wl,-search_paths_first -undefined error -o libtalloc.dylib.2.0.1 ./talloc.o ./libreplace/replace.o ./libreplace/snprintf.o ./libreplace/getpass.o ./libreplace/strptime.o -install_namelibtalloc.dylib.2
gcc: error: unrecognized command line option '-install_namelibtalloc.dylib.2'
make: *** [libtalloc.dylib.2.0.1] Error 1
Setting SONAMEFLAG to either "-install_name " (note trailing space), or
"-Wl,-install_name," results in a successful build. The latter seems
more clear.
