[Patch ARM] Fix PR target/61413 - definition of __ARM_SIZEOF_WCHAR_T

[Ramana Radhakrishnan]

Hi,

The ACLE 
http://infocenter.arm.com/help/topic/com.arm.doc.ihi0053c/IHI0053C_acle_2_0.pdf 
expects this macro to be defined in terms of byte sizes but we return 
bit sizes *and* additionally do not handle -fshort-wchar.

Applied to trunk.

regards
Ramana
