From: Pascal Huerst <pascal.huerst at gmail.com>
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/.

Changes v8 -> v9:
Add dependency on the host variant, needed to dump the symbols from
the processed files (Yann)
Cleanup and fix the script (do not pick system files!) (Yann)
Changes v7 -> v8
Removed use of eval in $(eval ls "${TARGET_DIR}/${@}"); do
as expected by Yann E. MORIN
Changes v6 -> v7
Removed comments I forgot to remove in v6 in gen-symy.sh for:
ifeq ($(BR2_PACKAGE_GOOGLE_BREAKPAD),y)
as suggested by Yann E. MORIN
Still using eval, however for:
for FILE in $(eval ls "${TARGET_DIR}/${@}"); do
could not make it work without eval
Changes v5 -> v6
google-breakpad: new package has been accepted.
Moved parts from makefile into google-breakpad.mk and defined
the call to gen-symy.sh as a new variable in google-breakpas.mk.
This seems to be more compatible with fabios series, as
suggested by Arnout and Thomas.
Changed integration in Config.in, by adding an enable google breakpad
option which expands to a list to insert filenames as suggested by
Arnout and Thomas.
Removed creation of tmp directory in gen-symy.sh as sugested
by Arnout, since this is not necessary.
Changes v4 -> v5 (All suggested by Yann E. MORIN)
Fixed some typo
Reorganized patch structure
which parts belong to 'new package' and which parts belong to
'intergration into Makefile and Config.in'
Changed and Rewrote gen-symy.sh - script
Passing $(EXTRA_ENV)
Adapted a proposed solution from Yann E. MORIN, which
uses ls instead of find commands
Made better descriptions for users in:
Config.in
package/google-breakpad/Config.in
Changes v3 -> v4
Fixed minor issue in google-breakpad_gen-syms.sh
Had to remove -print from find command
Changes v2 -> v3 (All suggested by thomas.petazzoni at free-electrons.com)
Removed dependency of BR2_ENABLE_DEBUG, but added comment,
that this flag might have to be set in order to use breakpad
properly.
Removed "find -name ..." for libs and binaries by generic patterns,
such as "*.so" and so forth. This will never work properly. Instead
I added a list to insert libs and binaries, that will be symbol-
dumped and prepared for breakpad (see Config.in patch v3 2/2)
Changed storage path for dumps from: $(TARGET_DIR).. to
$(STAGING_DIR)/usr/share/google-breakpad-symbols/
Removed most logic from Makefile. Added script instead, which is
called by Makefile
Added dependency for compatible targets: ARM, i386, MIPS...
Set fixed version for checkout (instead of head)
Fixed typos, and some minor mistakes
Changes v1 -> v2 (All suggested by maxime.hadjinlian at gmail.com)
Added dependency from BR2_ENABLE_DEBUG
Removed symbolstore.py -> Its all done in Makefile now
Removed new Target -> It in target-finalize before stripping now
Added LICENSE and LICENSE_FILE to *.mk
