The variables to make builds silent/verbose live inside
tools/build/Makefile.build. Move those variables to the top-level
Makefile.perf to be generally available.

Re-tested, now the lines below continue to appear, and also the 'make -C
tools/perf build-test' that was failiong on the first patch submission
is now ok as well, so I re issue my:

At this point this will go thru Namhyung, that will process patches
while I'm in vacation for perf-tools-next as well, thanks!

hi,
if we move this out of here, we need to fix other tools that rely on that,
bpftool and resolve_btfids do not build quietly now

but not sure what was the reason of moving it out, the code in Makefile.perf
seems same as the one above

thanks,
jirka

perf/Makefile.syscalls wanted to support quiet building. Makefile.perf
imports both Makefile.syscalls and Makefile.build, so I moved this quiet
infrastructure into Makefile.perf so that both of these files could use
it.

I was trying to move the quiet infrastructure higher up in the callchain
so that the code did not need to be duplicated. Perhaps it is better to
move this into a separate file that exports "quiet" and "Q" and then can
be imported from bpf/Makefile, perf/Makefile.perf, and any other tool
that wants to have quiet builds?
