Re: [RFT] Testing 1.22

Hello,

when building with system libbpf I get:

[   40s] make[1]: Nothing to be done for 'preinstall'.
[   40s] make[1]: Leaving directory '/home/abuild/rpmbuild/BUILD/dwarves-1.21+git175.1ef87b2/build'

[   40s]   as was expected.

[   40s] error: Bad exit status from /var/tmp/rpm-tmp.OaGNX4 (%install)

This is not a problem with embedded libbpf.

Using system libbpf seems to be new in 1.22

Thanks

Michal
