tools/power/cpupower: Add 64 bit library detection
The kernel-tools-lib rpm is installing the library to /usr/lib64, and not /usr/lib as the cpupower Makefile is doing in the kernel tree. This resulted in a conflict between the two libraries. After looking at how other tools installed libraries, and looking at the perf code in tools/perf it looks like installing to /usr/lib64 for 64-bit arches is the correct thing to do. Checks with 'ldd cpupower' on SLES, RHEL, Fedora, and Ubuntu result in the correct binary AFAICT: [root@testsystem cpupower]# ldd cpupower | grep cpupower libcpupower.so.0 => /lib64/libcpupower.so.0 (0x00007f1dab447000) Commit ac5a181d065d ("cpupower: Add cpuidle parts into library") added a new cpupower library version. On Fedora, executing the cpupower binary then resulted in this error [root@testsystem cpupower]# ./cpupower monitor ./cpupower: symbol lookup error: ./cpupower: undefined symbol: get_cpu_topology 64-bit libraries should be installed to /usr/lib64, and other libraries should be installed to /usr/lib. This code was taken from the perf Makefile.config which supports /usr/lib and /usr/lib64.
