perf build: Fix feature-dump checks, we need to test all features
I see problem with test-all case speedup, because it does not comprise checks for 32bits compilations, fix it. The problem could be noticed by calling: make -C tools/perf feature-dump That would end up misdetecting the feature-compile-x32, that, building using 'gcc -mx32' needs stub headers not present in a fedora 23 devel machine and thus fail to compile, but ended up appearing as detected, i.e. present in tools/perf/FEATURE-DUMP as 'feature-compile-x32=1'. With this fix it correctly appears as 'feature-compile-x32=0' and if we uninstall the libc devel files for 32 bits (glibc-devel.i686), then the relevant variable is flipped from 'feature-compile-32=1' to 'feature-compile-32=0'. The same things happened for bionic and libbabeltrace, that were misdetected because the are no tested in test-all.c Reported-and-Tested-by: Arnaldo Carvalho de Melo <> Signed-off-by: Jiri Olsa <> Cc: Wang Nan <> Link: Signed-off-by: Arnaldo Carvalho de Melo <>
