Successfully built gcc 4.3.1 toolchain using 4.1.1
Cannot rebuild 4.3.1 under itself, see error message below.
Same problem occurs when trying to build 4.3.2.

Looks similar to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29693 except:
- compiling for oabi not eabi
- building 4.3.x not 3.4.x

I wonder if this was fixed in 4.1.1, but there may be a regression with 4.3.x?  Otherwise I cannot explain how I managed to build 4.3.1 in the first place.
