Normally, auto-tooled packages like binutils have a default value for
CFLAGS that is typically "-g -O2" which means you get the debug
information. When creating binary packages for distribution the
binaries are typically stripped later.
This is just a long-winded way of saying that if you build with the
default configure options you should get debug information, and if not
use a CFLAGS override when calling configure.

It would help, since otherwise backtraces will only have raw addresses.
Note that the cygwin configure script[*] has a --enable-debugging
switch, but this is for enabling lots of runtime consistency checks and
extra verbosity -- it is not meant for enabling debug symbols, which you
should get by default.
[*] It's not in the toplevel configure, so it won't show up if you do
--help from there. But if you --help in the winsup/cygwin directory it
will show up, and you can still specify it at the top level where it
will be passed along.
