bfin gdb simulator

Hi,

when trying to use latest gdb or 7.10.1 to 
build bfin simulator, I get:
cc -DHAVE_CONFIG_H   -DWITH_DEFAULT_MODEL='"bf537"'  -DPROFILE=1
-DWITH_PROFILE=-1   -DWITH_DEFAULT_ALIGNMENT=STRICT_ALIGNMENT

gdb 7.9.1 works fine. I have not git bisect it. May be someone have
already an idea what has breaking it?

best regards
