qt: fix build on powerpc_e500mc
gcc bug internal compiler error: in validate_condition_mode, at
config/rs6000/rs6000.c:180744. Bug is fixed since gcc 7.
Workaround is to set -mno-isel, see
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60818 and
https://gcc.gnu.org/ml/gcc-patches/2016-02/msg01036.html
This bug is also raised on BR2_powerpc_8540, BR2_powerpc_8548 and
BR2_powerpc_e5500.
