ARM/Thumb long calls stubs

[OMakarenko]

The following examples doesn't work with 2.12 binutils:

>>>example1:
Thumb_func1(void)
{
}

Thumb_func2(void)
{
        Thumb_func1();
}

if the distance between func1 and func2 is happen to be more then 4M this
code fails.

Compiler generates: 

BL Thumb_func1

to call Thumb_func1 and linker doesn't see that it can not get to
Thumb_func1 with simple BL (it can only address +-4M in thumb mode)
It should generate some stub to call Thumb_func1 using register, shouldn't
it? Or it should report an error at least.

>>>example2, compiled with interwork
ARM_func(void)
{
}

Thumb_func(void)
{
        ARM_func();
}


Linker correctly adds interwrork stub but if the stub itself is too far from
Thumb_func() it fails to add long call stub again.

Does ld is supposed to support long calls stubs or not?
Are there any known workarounds?
