Samba's executables are making it to squashfs unstripped. I'm running with -g3, so it was more noticeable:

debug_size               file
772181      (0x000bc855) build_dir/target-mipsel_24kc_musl/root-ramips/usr/bin/pdbedit

Hrm, was using binutils 2.35.1 with strip --strip-unneeded --remove-section=.comment --remove-section=.note. When I run this manually, I get no change, so this is likely a binutils bug.

[daniel-santos]

OK, so the problem still exists with binutils 2.32, so re-opening. Everything in my build_dir/target*/root-ramips directory is stripped except for samba4 and libperl.so. Being that I've built with CONFIG_DEBUG, the result is 129.5MiB of total debug information in my rootfs.

Here's my ugly fix for you:

+RSTRIP:=do_strip() { find $$$$* -type f -executable | xargs -d '\n' $(TARGET_CROSS)strip --strip-unneeded || true; }; do_strip

 CONFIGURE_VARS += \
        CPP="$(TARGET_CROSS)cpp" \

I think I should really clean up the whole stripping mechanism and present it upstream. You can't just run around and snip out crap you don't like at random. I argued last year about the --strip-all being wrong, but now I see why that isn't breaking things -- if the rstrip.sh script detects it's relocatable, it treats it like a kernel module -- ugly.

Its related to this bug: #10783 and #10769

I had to disable the default rstrip script, since it breaks sambas private rpath.
