built gcc-4.4 branch libjava with a binutils from trunk and this patch applied, 
and passing --no-merge-exidx-entries, no regressions in the testsuite.  one 
build configured to default to armv4 by default, another one configured to armv7 
by default, and adding -marm.

recent gcj versions (>= 4.1?) don't work work with the old arm abi.

I'll recheck with 4.5 and trunk as time and build resources permit.
