The libbpf build system currently uses the output of "uname -m" to
determine if the library should be installed in "lib" or
"lib64". However, uname -m returns the architecture of the build
machine, which often has nothing to do with the target CPU
architecture.
A patch has been submitted and accepted upstream to address this
issue, by using the $(CC) -dumpmachine output instead. This ensures
libbpf is installed in either "lib" or "lib64" depending on the
bitness of the target CPU architecture.
