Subject[PATCH 1/1] libbpf: ensure F_DUPFD_CLOEXEC is defined
Date
This definition seems to be missing from some older toolchains.

Note that the fcntl.h in libbpf_internal.h is not a kernel header
but rather a toolchain libc header.

Fixes:
libbpf_internal.h:521:18: error: 'F_DUPFD_CLOEXEC' undeclared (first use in this function); did you mean 'FD_CLOEXEC'?
fd = fcntl(fd, F_DUPFD_CLOEXEC, 3);
^~~~~~~~~~~~~~~
FD_CLOEXEC
