I suppose you are using GCC version 4.7 or newer and have the gold linker installed. Linking QtWebKit using gold does not work with that GCC version, but the flag that sets it as the linker is added to QMAKE_LFLAGS anyway if gold is installed. 

A quick workaround for this is to edit the file src/3rdparty/webkit/Source/common.pri in your qt source tree and comment out the following lines with a #: 

#message(Using gold linker)
#QMAKE_LFLAGS+=-fuse-ld=gold

This will deactivate the gold linker.

Best regards,
Michael
