[klibc] udev no longer compiles (since 1.3.5)

[Aaron Griffin]

As the title suggests, udev no longer compiles under klibc versions > 1.3.5
It may partially be udev's fault, however, certain symbols, such as
SOCK_DGRAM, are no longer visible when compiling under klcc, which is
causing this issue.

A simple check of the linux/net.h header shows some
ARCH_HAS_SOCKET_TYPES define, which is not set internally by udev's
source.

Where would be the most appropriate place for this?  Should this be a
udev fix, or a klibc fix?

Thanks,
Aaron
