I'm very far from being an expert on any of this, but FWIW... it looks  
like you're getting lots of compile errors in fontconfig's  
fcfreetype.c, and I wonder if the root cause of these is that you have  
freetype 1 headers that are being found ahead of freetype 2 on your  
system. I see -I/usr/include/freetype2 there in your command line, but  
I don't know what else may be lying around....

Also, you might want to consider linking with the system's fontconfig  
library, even though you're compiling your own Cairo; if you're  
prepared to assume that all Linux distros you're targeting will have  
(some version of) fontconfig in a standard place, this may be more  
reliable than using a private, static-linked copy which may be  
incompatible with the configuration and font cache files belonging to  
the system's fontconfig. Your users will not thank you if your app  
stomps all over their system's font caches because you're shipping a  
different fontconfig version; nor will they appreciate it if you avoid  
this by using an entirely separate configuration, thereby forcing them  
to "install" fonts twice.
