Possible fix
Attached is a patch which appears to fix this issue for me (on gcc 4.8.3).
In gcc/Makefile.in there is a comment:
# The gengtype generator program is special: Two versions are built.
# One is for the build machine, and one is for the host to allow
# plugins to define their types and generate the supporting GGC
# datastructures and routines with GTY markers.
# The host object files depend on CONFIG_H, and the build objects
# on BCONFIG_H. For the build objects, add -DGENERATOR_FILE manually,
# the build-%: rule doesn't apply to them.
The change I chose to make swaps the make dependencies around, alternatively
GENERATOR_FILE may defined in the wrong case. I'm not sure what the right
behaviour is here, or which set of objects is which!
