They were derived from incorrect values cr=0.2125 (should be cr=0.2126)

Remove all Blackfin architecture optimizations
...
Blackfin is a painful platform to work with, no test machines are available
and the range of multimedia applications is dubious. Thus it only represents
a maintenance burden.

yuv2rgb: handle line widths that are not a multiple of 4.
...
This introduces support for width%4==2 in addition to width%4==0. For
odd widths, some more checks are needed, since the current code always
handles two luma items in a row, thus there is a possibility of an
overread by one.
