[Reproducible-builds] Bug#789842: FTBFS: PDFDocks.cpp.o: undefined reference to symbol '_ZNK11QDomElement9attributeERK7QStringS2_'

[Chris West (Faux)]

Source: texworks
Version: texworks_0.5~svn1363-5
Severity: serious
Tags: sid stretch
Justification: fails to build from source (but built successfully in the past)
User: reproducible-builds at lists.alioth.debian.org

Dear Maintainer,

The package fails to build, possibly due to updated gcc/ld toolchain being more picky about linker flags:
