In gnuradio-core/src/lib/swig/Makefile
there is no line
builddir = .
I only found these lines which could be interesting?
# swig flags
# -w511 turns off keyword argument warning
# "-outdir $(builddir)" writes all generated output files to
#   the local builddir (which should always be '.')
SWIG_PYTHON_FLAGS = -fvirtual -python -modern -keyword \
        -w511 -outdir $(builddir)

No, I had 1.3.35 and the same error occurs.

In gnuradio/Makefile.common there is no line with "builddir"
There is only:
# swig flags
# -w511 turns off keyword argument warning
# "-outdir $(builddir)" writes all generated output files to
#   the local builddir (which should always be '.')
SWIG_PYTHON_FLAGS = -fvirtual -python -modern -keyword \
        -w511 -outdir $(builddir)
