google-breakpad: integration into Makefile and Config.in 



Add a new config option that allows to specify a list of files
to dump symbols from, and generate a database of symbols, in
stagins/usr/share/google-breakpad/.

	  This option will enable the use of google breakpad, a

	  library and tool suite that allows you to distribute an

	  application to users with compiler-provided debugging

	  information removed, record crashes in compact "minidump"

	  files, send them back to your server and produce C and C++

	  stack traces from these minidumps.  Breakpad can also write

	  minidumps on request for programs that have not crashed.

	  You may specify a space-separated list of binaries and
