So, before this patch:
[acme@felicio linux]$ make -C tools/perf -f tests/make make_static
make: Entering directory `/home/acme/git/linux/tools/perf'
Testing Makefile
make[1]: Entering directory `/home/acme/git/linux/tools/perf'
- make_static: cd . && make -f Makefile DESTDIR=/tmp/tmp.aCtpIoMBDZ LDFLAGS=-static
make[1]: Leaving directory `/home/acme/git/linux/tools/perf'
make: Leaving directory `/home/acme/git/linux/tools/perf'
[acme@felicio linux]$
after I applied it it was failing, but now, running just the 'make_static'
target, it works, oops, trying to run it as plain 'build-test', i.e. randomly
picking the targets and running them all...
Also note that I'm not using O= at all, trying to check first if it works
without it, to avoid introducing a regression.
Ok, failed again, I was lucky and it was the second test to run, it seems some
cleanup is not being done wrt the python binding...
$ make -C tools/perf build-test
