perf tools: Build programs to copy 32-bit compatibility
perf tools copy VDSO out of memory. However, on 64-bit machines there
may be 32-bit compatibility VDOs also. To copy those requires separate
32-bit executables.
This patch adds to the build additional programs perf-read-vdso32 and
perf-read-vdsox32 for 32-bit and x32 respectively.
