sys-libs/ldb-2.1.4-r1 -python fails with

>>> Configuring source in /var/tmp/portage/sys-libs/ldb-2.1.4-r1/work/ldb-2.1.4 ...
 * abi_x86_32.x86: running multilib-minimal_abi_src_configure
 * EPYTHON is unset while calling waf-utils. This most likely means that

 * Please ensure that python-single-r1_pkg_setup is called in pkg_setup().

emerging with +python works as expected.

In ebuild python-single-r1_pkg_setup is called in pkg_setup as

  use python && python-single-r1_pkg_setup

but waf is called unconditionally. So either waf-utils eclass should be modified to use a python interpreter in order of preference when EPYTHON is not set instead of aborting or the ldb ebuild should be modified to unconditionally call  python-single-r1_pkg_setup as done in sys-libs/talloc or sys-libs/tevent. This probably concerns all in-tree ldb ebuilds.

Modified ebuild compiles for me as expected with -ptyhon.
