Steven's patch in r160039 did get me a past the error in java/except.c, however
then the bootstrap dies a few files later with:

------- Comment #4 from amylaar at gcc dot gnu dot org  2010-07-01 19:14 -------
Alternatively, we could hookize FLOAT_WORDS_BIG_ENDIAN, and make jcf-parse.c
include target.h so it gets access to the target vector.  This would also
be better since then the code in jfc-parse.c no longer depends on the target.

If there are concerns about the performance impact an real.c, we could leave
the interface for the targets to define FLOAT_WORDS_BIG_ENDIAN, and let real.c
use the macro directly, while requiring that front ends use the target hook
defined in targhooks.c .

I've bootstrapped and regtested current 4.6 w/ java on arm-linux-gnueabi with
this patch applied, and it solved the bootstrap failure with no regressions.
I also included it in bootstraps w/ java on powerpc64 and sparc64, again with
no regressions.
