Subject: [PATCH linux-next 1/2] tools/latency-collector: Check pkg-config install

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.

Fixes: 9d56c88e5225 ("tools/tracing: Use tools/build makefiles on latency-collector")
