1. I dowload latest qt-everywhere 5.3.0 tarball and extract it on my fully updated Debian x64 system.
2. I configure according to the instructions in the README file with the following options:

$./configure -prefix $PWD/qtbase -release -opensource -static -confirm-license -fully-process -c++11 -largefile -continue -silent -optimized-qmake -no-sql-db2 -no-sql-ibase -no-sql-mysql -no-sql-oci -no-sql-odbc -no-sql-psql -no-sql-sqlite2 -no-sql-tds -no-gif -no-nis -no-cups -no-iconv -no-dbus -reduce-relocations -no-eglfs -no-directfb -no-linuxfb -no-glib -no-kms -no-sql-sqlite -qpa xcb -nomake examples -nomake tests

3. Configure works for a while before it completes with the following tail:

$make -j9
make: *** No targets specified and no makefile found. Stop.
