From: Samuel Martin Date: Tue, 8 Dec 2015 23:11:14 +0000 (+0100) Subject: package/lttng-tools: fix static build X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e85a0bb03face4963b1e93b83cdb01066d68b79b;p=buildroot.git package/lttng-tools: fix static build Some unit tests depend on objects from src/common/. This patch makes sure to points to the location of the non-PIC object files. Otherwise, in case of static only build, the PIC object are not built, so the link will fail.
