 Unfortunately, this breaks the build for musl toolchains. Both the autoconf
test and the actual code in src/libnet_link_linux.c have stupid __GLIBC__ checks
which make it include linux/if_ether.h instead of the toolchain header, and that
triggers a failure because of multiple definitions. The fundamental solution is
to add AC_CHECK_HEADERS of netinet/if_ether.h and act accordingly. But for me
it's sufficient to just make it:

# PF_PACKET is always available on Linux, but build breaks for musl
ifneq ($(BR2_TOOLCHAIN_USES_MUSL),y)
LIBNET_CONF_OPTS = libnet_cv_have_packet_socket=yes
endif
