[Buildroot] [PATCH 1/1] google-breakpad: added package to buildroot

[Pascal Huerst <pascal.huerst@gmail.com>]

This adds all necessary host and target tools to use google-breakpad
within buildroot. If the package is selected, the symbols needed by
google-breakpad's stackwalk are deployed to:

output/images/google_breakpad_symbols
