Bug#822364: linux: FTBFS on sh4: #error __NR_bpf not defined. libbpf does not support your arch.
Source: linux
Version: 4.5.1-1
Severity: normal

Usertags: sh4
Hi!
Linux 4.5.1 fails to build from source on sh4 since it tries to build the libbpf
code which has not been ported to sh4 yet [1]:

Could you disable libbpf on sh4 for the time being?
Thanks,
Adrian
