I compared the current build log with one of the original build logs. The critical difference seems to be:
original build (take from arm64 log) ==================================== -- Checking for module 'pango' -- Found pango, version 1.40.1 -- Checking for module 'pangoft2' -- Found pangoft2, version 1.40.1 -- Found LTDL: /usr/lib/aarch64-linux-gnu/libltdl.so -- LTDL_INCLUDE_DIR = /usr/include -- LTDL_LIBRARY_DIR = /usr/lib/aarch64-linux-gnu -- LTDL_LIBRARIES = /usr/lib/aarch64-linux-gnu/libltdl.so -- Checking for module 'pangocairo' -- Found pangocairo, version 1.40.1 -- Not a Windows platform so setting wincairo driver to OFF. new build (private amd64 log) ============================= -- Checking for modules '' Must specify package names on the command line [... repeated 14 times) -- WARNING: pkg-config does not find pango. -- Checking for modules '' Must specify package names on the command line [... repeated 14 times] -- WARNING: pkg-config does not find pangoft2. -- Found LTDL: /usr/lib/x86_64-linux-gnu/libltdl.so -- LTDL_INCLUDE_DIR = /usr/include -- LTDL_LIBRARY_DIR = /usr/lib/x86_64-linux-gnu -- LTDL_LIBRARIES = /usr/lib/x86_64-linux-gnu/libltdl.so -- Checking for modules '' Must specify package names on the command line [... repeated 14 times] includedir = libdir = linkflags = cflags = -- WARNING: pango and/or cairo not found with pkg-config. Disabling cairo drivers. To enable these drivers you must install development versions of pango and cairo and/or set the environment variable PKG_CONFIG_PATH appropriately. -- Not a Windows platform so setting wincairo driver to OFF. So, for some reason, the pango libraries are not found anymore. pango1.0 1.40.2-1 was uploaded on 2016-08-30 (so, after the bug report). However, this may give a hint where to look next...
