objdump for old ARM7TDMI (ARMv4T) showing instructions for newer architectures?!

Hello! I care about the success of GNU very much and wanted some feedback on
what to do about a potential bug in objdump for ARM....
I'm examining the output of "objdump -D --target=binary -m arm7tdmi" and seeing
instructions that do not exist on the ancient ARM7TDMI cores.
For example, mrcc, blx and ldc2 only appeared in ARMv5 or later but I see them
in the output with command line switches above.
(I see same problems with "-m armv4t".)
I'm using version 2.19.1-multiarch from Ubuntu 9.04.
Is this a genuine bug or must I use different switches.
