[Buildroot] [PATCH v2 1/3] package/qt: disable Qt GUI module for NiosII

[Romain Naour <romain.naour@gmail.com>]

The libQtGui.so build triggers an ld error with Binutils 2.25.1 which should
be fixed with the upcoming Binutils 2.26 release. In the same time, the issue
has been reported [1].

Although the Binutils issue is not fixed yet, disable Qt GUI module on nios2
since it's unlikely used on this plateform [2].

Avoid (GCC 5.2 and Binutils 2.25.51):
http://autobuild.buildroot.net/results/c94/c945bce96966e5e39d093c4265058a66f749eea6

Avoid (GCC 4.9.3 and Binutils 2.25.1):
http://autobuild.buildroot.net/results/ca9/ca981c419bfedb38c591f6e75151a943bc9535ef
