You should be able to ignore this error. The problem is that the configure 
script makes qmake parse all .pro files, even those that are not used.

The -arch argument is no longer necessary. And the linux-g++-mx5x mkspec is 
not present, is this something you created?

Yes, it seems too long...

You could try first including ../linux-g++/qmake.conf and changing only what 
you need. This is my old mkspec for compiling for MeeGo ARM:

include(../linux-g++/qmake.conf)

QMAKE_CC = armv7hl-meego-linux-gnueabi-gcc
QMAKE_LINK_C = armv7hl-meego-linux-gnueabi-gcc
QMAKE_LNK_C_SHLIB = armv7hl-meego-linux-gnueabi-gcc

QMAKE_CFLAGS += -march=armv7-a -mfpu=neon -Wno-psabi
QMAKE_CFLAGS_RELEASE   = -O3 -g

QMAKE_CXX = armv7hl-meego-linux-gnueabi-g++
QMAKE_LINK = armv7hl-meego-linux-gnueabi-g++
QMAKE_LINK_SHLIB = armv7hl-meego-linux-gnueabi-g++

QMAKE_CXXFLAGS        += $$QMAKE_CFLAGS
QMAKE_CXXFLAGS_RELEASE = $$QMAKE_CFLAGS_RELEASE

QMAKE_LFLAGS     += $$QMAKE_CXXFLAGS
QMAKE_LFLAGS_RELEASE += $$QMAKE_CXXFLAGS_RELEASE

QMAKE_AR = armv7hl-meego-linux-gnueabi-ar cqs
QMAKE_OBJCOPY = armv7hl-meego-linux-gnueabi-objcopy
QMAKE_RANLIB = armv7hl-meego-linux-gnueabi-ranlib


The qplatformdefs.h is just #include "../linux-g++/qplatformdefs.h".
