For what it's worth I have no problem building Emacs master on Fedora 25 
x86-64. I configured with './configure --enable-gcc-warnings 
--with-cairo'. The command 'ldd -v src/temacs' outputs the attached 
file. The symbol cairo_surface_set_device_scale is defined in the file 
/lib64/libcairo.so.2.11400.8.The other two symbols you had trouble with 
are defined in the file /lib64/libfontconfig.so.1.9.2. These are 
supplied by the packages cairo-1.14.8-1.fc25.x86_64 and 
fontconfig-2.12.1-1.fc25.x86_64, respectively. So perhaps the following 
command will help fix your problem:

dnf install cairo-devel fontconfig-devel
