[patch] ARM Thumb object symbols.

[Paul Brook]

gas currently gives gives non-function symbols declared in thumb code areas 
type STT_ARM_16BIT. The EABI does not define this symbol type, so these 
symbols should be left with their default type (usually STT_NOTYPE).

The patch below implements this.

Tested with cross to arm-none-eabi.
My previous patch to make objdump smarted is required to avoid testsuite 
regressions.
Ok?
