No. linux_device_pre.conf uses CROSS_COMPILE for other tools, too (ar, 
objcopy, ...).

# modifications to g++-unix.conf
QMAKE_CC                = $${CROSS_COMPILE}gcc
QMAKE_CXX               = $${CROSS_COMPILE}g++
QMAKE_LINK              = $${QMAKE_CXX}
QMAKE_LINK_SHLIB        = $${QMAKE_CXX}

# modifications to linux.conf
QMAKE_AR                = $${CROSS_COMPILE}ar cqs
QMAKE_OBJCOPY           = $${CROSS_COMPILE}objcopy
QMAKE_NM                = $${CROSS_COMPILE}nm -P
QMAKE_STRIP             = $${CROSS_COMPILE}strip
