[Buildroot] [PATCH] gpsd: work-around ICE when compiling for microblaze with GCC5

[Sergio Prado]

GCC 5.X generates an ICE when compiling gpsd for microblaze due
to optimizations, so lets disable it for now to works around
this problem.

A bug was reported to the gcc bug tracker:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68485
