Commit Message

  The target is to allow the tool to always enable the perf register
feature for native parsing and cross parsing, and current code doesn't
depend on the macro 'HAVE_PERF_REGS_SUPPORT'.

This patch remove the variable 'NO_PERF_REGS' and the defined macro
'HAVE_PERF_REGS_SUPPORT' from the Makefile.
