Sometimes it may be desirable to keep debug symbols for some binaries and
libraries on the target. This commit introduces the config option
BR2_STRIP_EXCLUDE_FILES, which is interpreted as a list of such binaries
and libraries, and the option BR2_STRIP_EXCLUDE_DIRS, which indicates
directories excluded from stripping entirely.
These exclusions are passed to the find command in the target-finalize step.

v5: line up with latest git
v4: whitespace changes
v3: merge with redundant patch 'stripping: use findfileclauses utility function'
v2: add the possibility to exclude entire directories
