Commit Message

Yauheni Kaliuta May 27, 2020, 7:16 a.m. UTC
Using one shell for the whole recipe with long lists can cause

make[1]: execvp: /bin/sh: Argument list too long

with some shells. Triggered by commit 309b81f0fdc4 ("selftests/bpf:
Install generated test progs")

It requires to change the rule which rely on the one shell
behaviour (run_tests).

Simplify also INSTALL_SINGLE_RULE, remove extra echo, required to
workaround .ONESHELL.
