[Buildroot] Adding libev to buildroot

[Yegor Yefremov <yegor_sub1@visionsystems.de>]

Hello Bernhard,

> Keep your good work going, thank you!

Thank you for the patch. Some remarks below:

1. the patches should be sent "inline", so it is easier to comment on them
2. your' Signed-off-by is still missing (see other patches on the list)
3. don't use :=, use = instead
4. this is autotools based package, so following template should be used http://buildroot.uclibc.org/buildroot.html#autotools-tutorial

I've reworked your patch. So please execute "make clean" or remove all files installed by installation of libev and test it with reworked patch.

Yegor
