Comment:

 Very very strange. Ok what I did is on sage.math.washington.edu:

 I downloaded:
 
http://boxen.math.washington.edu/home/release/sage-4.7.2.alpha2/sage-4.7.2.alpha2.tar
 Extracted the file and did
 make build
 using environment variables MAKE=make -j20 and
 SAGE_SPKG_PARALLEL_BUILD=yes.
 After having made this clean build (located in
 /mnt/usb1/scratch/mderickx/sage-4.7.2.alpha2) I got:

 {{{
 mderickx@sage:/mnt/usb1/scratch/mderickx/sage-4.7.2.alpha2$ ./sage -t
 --long "devel/sage-main/sage/rings/polynomial/pbori.pyx"
 sage -t --long "devel/sage-main/sage/rings/polynomial/pbori.pyx"
          [7.0 s]

 ----------------------------------------------------------------------
 All tests passed!
 Total time for all tests: 7.0 seconds
 }}}
 Then I qimported and applied your two patches and did
 {{{
 mderickx@sage:/mnt/usb1/scratch/mderickx/sage-4.7.2.alpha2/devel/sage$
 ../../sage -bt --long "devel/sage-main/sage/rings/polynomial/pbori.pyx"

 So I seem to not be able to reproduce your passing the doctest.
 Did you also use sage.math. I can give you acces to the created folder on
 sage.math so you can fiddle around with it.
