[Interest] Building Qt 5.5.1 on CentOS 5

I am trying to build Qt 5.5.1 on CentOS 5. I suspect that we don't need 
linuxfb, but there doesn't seem to be an easy way to skip this.

However, I get the following error:
/home/simon/rpms/build/qt-everywhere-opensource-src-5.5.1/qtbase/src/plugins/platforms/xcb/gl_integrations

In order to get this far, I have done the following:
1. installed extra packages as described on this page:
http://kate-editor.org/2014/12/22/qt-5-4-on-red-hat-enterprise-5/

2. Copied /usr/include/sys/signalfd.h from a CentOS6 system to the same 
location on my CentOS5 build machine.

3. Made the following changes to the source:
sed -i 's/#define QTESTLIB_USE_PERF_EVENTS/#undef 
QTESTLIB_USE_PERF_EVENTS/g' qtbase/src/testlib/qbenchmark_p.h
sed -i 's/getbyte/getc/' 
qtwebkit/Source/JavaScriptCore/offlineasm/offsets.rb
sed -i 's/| O_CLOEXEC//' 
./qtwebkit/Source/WebKit2/Platform/unix/SharedMemoryUnix.cpp

4. Made sure that python26 is used.

5. Used the following configure command:
./configure -R ‘\\\$$ORIGIN’ -D _X_INLINE=inline -D
