I'm building on Ubuntu 14.04, for ar71xx and au1000 targets. The problem
happens in OpenWRT 14.07 and trunk.

It looks like the host gcc gets called with the target CFLAGS, see the
config.log below. Tell me if there is anything else you need to know.

1 - I will see what I can do to make alsa-lib optional for various configs.

2 - Building alsa-lib has no dependency on the host system's audio setup. 
The problem you are seeing is indeed a problem with your build environment, 
and what tools you have installed. More information is needed about our 
build system and target config before I can help you.

Subject: Problems with ffmpeg and alsa-lib

Hello,

I have two problems with libffmpeg and alsa-lib, both in trunk and BB:

1) Is that libffmpeg always selects alsa-lib, even when I only select
libffmpeg-mini. According to the Makefile only libffmpeg-full is
supposed to depend on alsa-lib. If i remove that dependency from
libffmpeg-full in the Makefile I can compile all variants... What's
wrong here? and is the alsa-lib dependency really needed?

2) I can not compile alsa-lib on my platforms (ar71xx and au1000 - both
don't have a sound card), it fails with the following error:

checking for mips-openwrt-linux-gcc... gcc
checking whether the C compiler works... no
configure: error: in
`/home/br1/dev/openwrt/trunk/openwrt/build_dir/target-mips_34kc_uClibc-0.9.33.2/alsa-lib-1.0.28':
configure: error: C compiler cannot create executables

This does not look related to having a sound card or not :(

In the meanwhile I have solved the problems by removing the alsa-lib
dependency... Any ideas for a real fix?
