Introduce the libtraceevent library, that used to be bundled with the
trace-cmd tool. This library is now used by several tools and libraries
such as trace-cmd, libtracefs and rtla.

This package tries to install libraries in /usr/local/lib by default,
hence the redefinition of the "prefix" variable, so that the library
gets installed in "/usr/lib" instead.

The same applies to the pkgconfig handling of the proved Makefile, which
installs the .pc files in the /usr/local area by default, hence the
redefinition of the pkgconfig_dir to either the correct directory within the
staging area, or to empty value for the target to avoid installing the .pc
in that case.

+	bool "libtraceevent"
+	help
+	  libtraceevent is a library that interfaces with the ftrace
+	  subsystem in the linux kernel.
+	  It used to be bundled directly in the trace-cmd
+	  tool, but it was eventually extracted so that it can be used
+	  by multiple other tools and libraries, such as libtracefs and
+	  rtla.
