You would rerun the configure call with the --disable-stripping flag and 
--enable-debug.  with --enable-debug, the --help flag indicates that it 
accepts an =level, where level is simply text? appended to the -g flag 
passed to the assembler and compiler.  so --enable-debug=gdb would 
create a compiler flag of -ggdb, if you needed to specify whatever it is 
that this specifies.  I don't know if you need to leave it blank for -g, 
or remove the = sign, or if -g is default.

If you want to reuse your old configure line, do a head of config.mak, 
and that will give you the last configure line that was run, so you can 
copy paste and add the new flags and go from there.
