yes

We could have configure make the suggestion, but lets not require it.

Nah, just update the test of when the replacement code is used, it 
already works for plenty of systems at the moment.

This is the original source of the replacement code, although its probably 
a bit out of date.

maybe

ugh, less dependencies please ;)

Lets just add "linux/netlink.h" (and others) to the AC_CHECK_HEADERS list 
in the configure.in and add 'defined(HAVE_LINUX_NETLINK_H)' to the test in 
replace/getifaddrs.c.
