Subject: [PATCH libgloss/arm] discourge the use of blx when it's not supported

Hi,
In libgloss/arm/crt0.S, the blx is used when (__thumb__ ) || (__thumb2__)
defined, 
unfortunately it breaks compilation of libgloss for targets which do not
support it, like armv4t.
Moreover this patch clears the use of blx on all arm targets.

Is it OK?

Thanks-chengbin

                 * arm/crt0.S: Don't use blx for pre-armv5 targets.
