musl doesn't implement argp.h and requires an explicit lib for it, so we must test for -largp presence and use it if appropriate Signed-off-by: Dominique Martinet <[email protected]>

DEFFILEMODE is not defined on musl libc.
Linus has expressed preference towards using explicit octal value in
the past over combinaisons of S_Ix{USR,GRP,OTH}, so just replace it
with 0666 directly

musl nftw implementation does not support FTW_ACTIONRETVAL. There have been multiple attempts at pushing the feature in musl upstream but it has been refused or ignored all the times: https://www.openwall.com/lists/musl/2021/03/26/1 https://www.openwall.com/lists/musl/2022/01/22/1 In this case we only care about /proc/<pid>/fd/<fd>, so it's not too difficult to reimplement directly instead, and the new implementation makes 'bpftool perf' slightly faster because it doesn't needlessly stat/readdir unneeded directories (54ms -> 13ms on my machine) Signed-off-by: Dominique Martinet <[email protected]>
musl does not like including sys/fcntl.h directly:
1 | #warning redirecting incorrect #include <sys/fcntl.h> to <fcntl.h>
