tools/perf/build: Pass through DEBUG parameter
Arnaldo reported that 'make DEBUG=1' does not work anymore.
The reason is that 'Makefile' only passes it through to
'Makefile.perf' via the environment, but 'Makefile.perf'
checks that it's a command line option:
ifeq ("$(origin DEBUG)", "command line")
PERF_DEBUG = $(DEBUG)
endif
So pass it through properly, and also clean up DEBUG parameter
handling while at it and fix a couple of annoyances:
- DEBUG=0 used to be interpreted as 'debugging on'. Turn it
into 'debugging off' instead.
- Same was the case for 'DEBUG=' - turn that into debug-off
as well.
- Pass in just a clean, sanitized 'DEBUG' value and get rid of
the intermediate, unnecessary PERF_DEBUG variable.
