Not sure if this is a problem.
Qt 0.16.3 runs successful on Ubuntu Trusty (14.04.5).
However, Qt 0.17.0rc4 (and master) gives me undefined symbol: FT_Get_Font_Format:
0.17.0rc4:
user@ubuntu:~/Desktop$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.5 LTS
Release: 14.04
Codename: trusty
user@ubuntu:~/Desktop$ ./bitcoin-qt --regtest
./bitcoin-qt: symbol lookup error: ./bitcoin-qt: undefined symbol: FT_Get_Font_Format
Could you please dump the output of ldd bitcoin-qt as well as readelf -d bitcoin-qt ?
Looks like the Fontconfig abi might've changed :\

This is an issue with qt's usage of freetype.
A few years ago, libfreetype introduced FT_Get_Font_Format as an alias for FT_Get_X11_Font_Format, but FT_Get_X11_Font_Format was kept for back-compat.
Our last qt bump introduced a call to FT_Get_Font_Format. I think that if it used the old name, it would be back-compat to older runtime freetype libs. @jonasschnelli Can you give this quick (untested) hack a try?

@theuni I spun up a new 14.04.5 Ubuntu VM and cloned af4b8a3.
Doing a depends build, and running bitcoin-qt results in the same error as @jonasschnelli (make check fails):
After applying your patch and re-building, make check passes and bitcoin-qt runs:

That's all I tested.
