This includes all default features of FFmpeg (and a few 
external libraries).
If you want smaller libraries, you have to change your 
FFmpeg configure line (it cannot help if you change 
something about your linking command for your own 
application x2pcm, that cannot work!) - since you did 
not explain exactly which features you need, I can 
only guess but I suggest you start with a line like 
the following and test, you will find many missing 
features:
$ ./configure --disable-everything --enable-protocol=file 
--enable-demuxer=aac,mp3 --enable-parser=aac,mpegaudio 
--enable-decoder=aac,mp3 --enable-encoder=pcm_s16le 
--enable-muxer=wav,pcm_s16le

Please understand that this is certainly not exactly 
what you need, it is meant to help finding the right 
options.
You can further decrease the size of the libraries by 
using --disable-all instead of --disable-everything 
but you need to enable even more features in that case.

--disable-debug should not be necessary since I expect 
you will strip your final executable anyway, but you 
can of course add it to configure as well.

Please google for "top-posting" and please avoid it here, 
it is considered rude.
