    build speedup: Do not use shell 'find' function to look for NOTICE files. · 3e0e611e

    The GNU Make wildcard function can be used to look for a specific file and
    is _much_ faster than invoking the find command through $(shell ...).
    
    Since notice_files.mk is included by base_rules.mk for each and every module
    in the build tree, this represents a considerable speed-up. For example, when
    building the full-eng product from the AOSP tree, the no-op "make" goes from
    21 seconds to 16 seconds with this patch applied.
