[Buildroot] Replace libev with libuv

[Nimai Mahajan]

I got it. Gustavo, took a slightly different approach but this works
(idea taken from sdl.mk, which also has a broken build process):

LIBUV_VERSION = v0.11.26
LIBUV_SITE = $(call github,joyent,libuv,$(LIBUV_VERSION))
LIBUV_DEPENDENCIES = host-pkgconf
LIBUV_INSTALL_STAGING = YES
LIBUV_AUTORECONF = YES
LIBUV_LICENSE = BSD-2c, BSD-3c, ISC, MIT
LIBUV_LICENSE_FILES = LICENSE

# Tweaked autogen.sh
#define LIBUV_FIXUP_AUTOGEN
#    echo "m4_define([UV_EXTRA_AUTOMAKE_FLAGS], [serial-tests])" >$(
<at> D) m4/libuv-extra-automake-flags.m4
#endef

define LIBUV_RUN_AUTOGEN
    cd $(@D) && PATH=$(HOST_PATH) ./autogen.sh
endef

LIBUV_POST_PATCH_HOOKS += LIBUV_RUN_AUTOGEN

$(eval $(autotools-package))

Hope this helps others out.
