Thanks for reviving this patch, definitely appreciated!

One question: we received only PATCH 4/5 and PATCH 5/5 from your
series. Is this normal? Maybe it's just a small mistake on your side
when generating the patches.

Some comments below.

I'd x264 is mostly a library, so I'd prefer to see it in the libraries.

The license is actually GPLv2+.

Line not needed.

Might be worth adding a comment right before X264_CONFIGURE_CMDS to
indicate that the configure script is not generated by autoconf.

--enable-shared will not work for static only builds. Maybe you should
try something such as:

X264_CONF_OPTS = --enable-static

ifeq ($(BR2_PREFER_STATIC_LIB),)
X264_CONF_OPTS = --enable-pic --enable-shared
endif

and then use $(X264_CONF_OPTS) when calling the configure script.

If you want to try a purely static configuration, you can try with the
basic configuration at
http://autobuild.buildroot.org/toolchains/configs/bfin-uclinux.config.

Could you try:

	$(TARGET_MAKE_ENV) $(MAKE) $(TARGET_CONFIGURE_OPTS) -C $(@D)

 ?

CC="$(TARGET_CC)" as well as many other useful variables are passed in
$(TARGET_CONFIGURE_OPTS). It's also a good habit to pass
$(TARGET_MAKE_ENV) in the environment.

Also pass $(TARGET_MAKE_ENV).

Ditto.

Could you respin after fixing those minor issues?

Thanks!
