Subject: sdk: use bundle-libraries.sh to ship kernel objtool tools
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=efaaadb49e90b51ba3a6adc6fafc330c23b8f764;p=oweals%2Fopenwrt.git

sdk: use bundle-libraries.sh to ship kernel objtool tools

Ensure that the kernel objtool utilities are processed by the library
bundler in order to ensure that they're usable on foreign systems with
different libc versions.

Fixes: a9f6fceb42 ("sdk: fix building external modules when CONFIG_STACK_VALIDATION=y")
