It's configurable. See the GDB 7.5 builder configuration

         'factory' :
run_modern_gdb=True, clean=False)},

The "clean=False" bit will configure the builder not to clean the
build (& not to run configure if there's already a makefile)

Yep, on the times I've had problems with this I've just gone onto the
builder & nuked the obj directory which causes the buildbot to do a
full clean build next time
