------------------
From: Tao Chen chen.dylane@linux.dev
[ Upstream commit 26ebba25e210116053609f4c7ee701bffa7ebd7d ]
The tool pkg-config used to check libtraceevent and libtracefs, if not installed, it will report the libs not found, even though they have already been installed.
Before: libtraceevent is missing. Please install libtraceevent-dev/libtraceevent-devel libtracefs is missing. Please install libtracefs-dev/libtracefs-devel
After: Makefile.config:10: *** Error: pkg-config needed by libtraceevent/libtracefs is missing on this system, please install it.
