ec6a1ac308 Fix IPv4 address in replies to A or NS queries (github issue #38) 
The destination field in struct query was changed from in_addr_t to
struct sockaddr_storage, wihtout updating the functions sending it
in src/dns.c.

Only add extra A answer for NS queries if destination refers to an
IPv4 address, and fail if trying to encode a reply to an A query
if destination is not IPv4.

This means NS requests received over IPv6 will not contain an address
and A requests will be ignored, unless the -n option is used, or the
www subdomain is requested which sets a fixed address (127.0.0.1).

be0735d7c7 documentation: make it clear, what incompleteness -b has 
AXFR does not pass through iodine (sounds reasonable), so we should
recommend in the README.md to keep the original dns server in front if
zone transfers are required.

024481c94b Fix cross compilation 
src/osflags hard codes the build architecture pkg-config. After making it
substitutable and substituting it from the build environment, iodine cross
builds successfully.

https://bugs.debian.org/921822, adjusted to Git HEAD.
