Some packages install binaries into /lib and /usr/lib which aren't marked as executable and hence aren't getting stripped, wasting image size. I've posted a fix for libgcc but we need to: a) Have better sanity tests for this (unstripped binaries) b1) Either warn about non-executable files in the libdirs b2) Process files in the libdirs regardless of the executable bits
Fixed in master with http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=81ac27598414a7a9bf6bee747c8c0020ac88ed25
