From: Florian Fainelli Date: Tue, 23 May 2017 02:35:00 +0000 (-0700) Subject: uml: Check for glibc static libraries X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fstaging%2Fluka.git;a=commitdiff_plain;h=e8c3b9897363641614bcb461b6ca704b95422da6 uml: Check for glibc static libraries UML statically links against libutil, librt and libpthread. Some hosts do not necessarily have these libraries installed and we should find out sooner than later (during the final vmlinux linking stage) about that.
