Comment:

 I have this line in my /usr/qt/3/mkspecs/linux-g++/qmake.conf file:
 QMAKE_LFLAGS_RELEASE=-Wl,--hash-style=both,-z,relro,--enable-new-
 dtags,-O1,-z,now,--as-needed

 My machine is an AMD64 running GCC 4.2.2, binutils 2.18, and qt 3.3.8.

 When I build mythtv 15429, this is the error I get:

 If I remove the "--as-needed" from the QMAKE_LDFLAGS_RELEASE line in
 qmake.conf, mythtv builds and runs fine.
