Thanks for your patch. However, I don't really understand why it is
necessary. Even without your patch, the .pyc files for python3 are
properly generated in usr/lib/python3/, and there is no __pycache__
folder anywhere.

I've built the following configuration:

BR2_arm=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y
BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.org/toolchains/tarballs/br-arm-full-2016.08-613-ge98b4dd.tar.bz2"
BR2_TOOLCHAIN_EXTERNAL_GCC_4_8=y
BR2_TOOLCHAIN_EXTERNAL_HEADERS_3_10=y
BR2_TOOLCHAIN_EXTERNAL_LOCALE=y
# BR2_TOOLCHAIN_EXTERNAL_HAS_THREADS_DEBUG is not set
BR2_TOOLCHAIN_EXTERNAL_INET_RPC=y
BR2_TOOLCHAIN_EXTERNAL_CXX=y
BR2_INIT_NONE=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_PYTHON3=y
# BR2_PACKAGE_PYTHON3_PY_ONLY is not set
BR2_PACKAGE_PYTHON3_PYC_ONLY=y
# BR2_PACKAGE_PYTHON3_PY_PYC is not set
BR2_PACKAGE_PYTHON_CRCMOD=y
# BR2_TARGET_ROOTFS_TAR is not set

And it gives the following list of .pyc files in output/target:
