Package: qmake-qt5 Version: 5.4.2+dfsg-2 Severity: important
this is seen when building openjfx on arm64: https://launchpadlibrarian.net/220388096/buildlog_ubuntu-wily-arm64.openjfx_8u60-b27-0ubuntu1_BUILDING.txt.gzbuild.gradle chooses to set the linux-g++-m64 spec, and then fails on the unknown -m64 option. Trying to use the linux-g++ option fails, because the qplatformdefs.h of this spec is basically empty. This file is identical for the -m32 and -m64 specs, so why not include it there?
