[Buildroot] [PATCH 1/1] msmtp: don't try to use IDN feature

[Anthony Viallard <viallard@syscom-instruments.com>]

I don't known if there is a consensus about IDN usage for buildroot. I
didn't see an option in the config about it. I presume IDN should be
disabled for all package, am I right ?

autoconf can't see if AI_IDN is really supported (http://sourceforge.net/p/msmtp/code/ci/907916e8089ea9303a7c091b763087530c88a063/).
It seems weird but this is the case apparently.

Before I did the above patch, msmtp failed to send mail. The output was:

msmtp: cannot locate host smtp.mandrillapp.com: Bad value for ai_flags
