[PATCH 1/2] bind: enable threads support and use epoll

[<kai.kang@windriver.com>]

From: Kai Kang <kai.kang@windriver.com>

Disable threads support for bind is inherited from legacy openembedded.
And all libc's support proper threading on Linux now, so enable threads
support for bind.

But static libraries cause package dhcp fails to compile after enable
threads support. So enable to build shared libraries rather than static
libs to fix the failure.

Options devpoll and epoll are configured to choose most preferable
multiplex method for unix socket. The priorities are: epoll > poll >
select. When set '--enable-epoll', it just defines a var and include
header file that is available for cross compile. So use epoll for bind.
