ffmpeg null filter when configuring (no such filter 'eq')

I configure ffmpeg to compile it an Android gcc (among others) like that:

./configure --disable-filters --enable-filter=atrim,trim,eq

And this is the preview:

Enabled filters:
aformat          anull            atrim            format           null             trim

Obviously the eq filter is missing and in it's place it's the null enabled filter. As expected the eq filter is also missing from the executable binary and if we try use the eq filter it will return:

 No such filter: 'eq', Error reinitializing filters!, Failed to inject frame into filter network: 
 Invalid argument, Error while processing the decoded data for stream #0:0, Conversion failed!

Full configuration:

--prefix=/path/to/x86 
--enable-static --disable-shared 
--enable-small 
--enable-cross-compile 
--target-os=linux
--arch=x86 
--sysroot=/path/to/sysroot 
--cross-prefix=/path/to/i686-linux-android- 
--enable-pic 
--disable-ffplay 
--disable-ffprobe 
--disable-ffserver 
--disable-doc 
--disable-filters 
--enable-filter=atrim,trim,eq 
--disable-asm 
--disable-debug
--extra-cflags=-I/path/to/usr/include -O3 -Wno-deprecated-declarations -fpie -pie -Wl,-z,relro,-z,now -march=i686 -m32 -mtune=intel -mssse3 -mfpmath=sse
--extra-ldflags=-L/path/to/usr/lib -fpie -pie

The eq filter requires FFmpeg to be compiled under the GPL license, so add --enable-gpl.
