[ Upstream commit c363eb48ada5cf732b3f489fab799fc881097842 ] With some shells, the command construed for install of bpf selftests becomes too large due to long list of files: make[1]: execvp: /bin/sh: Argument list too long make[1]: *** [../lib.mk:73: install] Error 127 Currently, each of the file lists is replicated three times in the command: in the shell 'if' condition, in the 'echo' and in the 'rsync'. Reduce that by one instance by using make conditionals and separate the echo and rsync into two shell commands. (One would be inclined to just remove the '@' at the beginning of the rsync command and let 'make' echo it by itself; unfortunately, it appears that the '@' in the front of mkdir silences output also for the following commands.) Also, separate handling of each of the lists to its own shell command. The semantics of the makefile is unchanged before and after the patch. The ability of individual test directories to override INSTALL_RULE is retained.
