Currently, the macro HAVE_PERF_REGS_SUPPORT is used as a switch to turn on or turn off the code of perf registers. If any architecture cannot support perf register, it disables the perf register parsing, for both the native parsing and cross parsing for other architectures. To support both the native parsing and cross parsing, the tool should always build the perf regs functions. Thus, this patch removes HAVE_PERF_REGS_SUPPORT from the perf regs files.
