I'm guessing this one is "No rule to make target `first'"

Up until here, everything looked fine. Starting on the next line, things start 
to get really freaky:

-IIBRARY_PATH, -IOLLECT_GCC_OPTIONS, -IOMPILER_PATH?

Can you attach you mkspecs/qconfig.pri after configure finished running?

Another freaky -I option.

There was a -v above from one the "COLLECT_GCC_OPTIONS", which caused moc to 
simply print its version and exit.

I'm not sure it's because of Chinese, but it's a very good candidate. Can you 
retry the following combinations:

 a) run configure as you have, but run switch to English (export LC_ALL=C) 
before running make
 b) run configure in English (export LC_ALL=C) but make in Chinese
 c) run both in English

The problem is that configure runs gcc with some special options and tries to 
parse the default include dirs, which is stored in QMAKE_DEFAULT_INCDIRS in 
mkspecs/qconfig.pri. That failed spectacularly. It could be because of your 
Chinese language or it could be something else with your GCC.

So, can you also attach the output of:
	gcc -xc++ -v - < /dev/null 2>&1 > /dev/null
