"make V=1" told 


 uic -qt5 -o libgui/src/ui-settings-dialog.h
../octave/libgui/src/settings-dialog.ui 
Unknown option 'qt5'. 
make: *** [libgui/src/ui-settings-dialog.h] Error 1 


As Mike wrote in the ML,


On my Debian system, uic is a symlink to a program called "qtchooser". This
program takes a -qt4 or -qt5 option and acts as a proxy to the real uic
program which is installed outside of PATH. 


I needed to erase the value "-qt5" from UICFLAGS, RCCFLAGS, MOCFLAGS, and
LRELEASEFLAGS in Makefile  to build octave.

This issue is due to current configuration not taking into account the case
that uic, rcc, moc, and lrelease are not proxy but real ones.
