Here's the relevant section:
Determining machine byte-order...
(/Users/chris/Developer/Applications/qtbase/mkspecs/macx-g++ yes
/Users/chris/Developer/Applications/qtbase
/Users/chris/Developer/Applications/qtbase)
g++ -c -pipe -O2 -Wall -W -I../../../mkspecs/macx-g++ -I. -o
endiantest.o endiantest.cpp
g++ -headerpad_max_install_names -o endiantest endiantest.o
strings: object: ./endiantest malformed object (unknown load command 9)
strings: object: ./endiantest malformed object (unknown load command 9)
After this I did the following shell commands:
cd config.tests/unix/endian
g++ -c -pipe -O2 -Wall -W -I../../../mkspecs/macx-g++ -I. -o
endiantest.o endiantest.cpp
g++ -headerpad_max_install_names -o endiantest endiantest.o
./endiantest
# this resulted in "Bus error"

./configure --help results in:
Installation options:
-qpa ................ This will enable the QPA build.
QPA is a window system agnostic implementation of Qt.
This seems to imply that -qpa is off by default. There is no "*"
default next to it.

Ok.
