This breaks:
LD_PRELOAD=/usr/local/x264-10/lib/libx264.so.146  ./ffmpeg -i ~/videos/mm-short.mpg -avcintra-class 100 -tune psnr -flags +ildct-global_header -t 0.5 -pix_fmt yuv422p10 -vf scale=1920:1080  -an x.mov

previously it encoded with high bit depth after the patch it attempts to use 8bit
and fails:
[libx264 @ 0x3c36a80] This build of x264 requires high depth input. Rebuild to support 8-bit input.

IIUC this patch changes from the value at runtime to the value at
build time. That seems like a bad idea as they can differ and the value
of the library linked to is the one mattering
