Easier to use the proper C macro.

Pass HAVE_RLIM_T via TARGET_CPPFLAGS since configure uses that define
but never actually declares it.

Without doing that, `config.h` tries to declare `rlim_t` itself which
leads to `config.h:126:16: error: 'long long long' is too long for GCC`
with musl on at least x86_64.

Also refresh patches while we're at it.

Use right size of addresses in bind() call. Also use getpeername addresses when
connecting to ident service to prevent address family mismatch between socket(),
bind() and connect() calls.
