how to compile glibc to pure arm instructions?

[Liu hua]

Hi guys,

When I compile eglibc for ARM32 platform. I find ports/sysdeps/arm/armv6t2/memchr.S
allways be translated to thumb instructions. There is a macro named "NO_THUMB" in
this file. However I can't define this NO_THUMB through configration.

So my question is how can I compile glibc into pure arm instructions through
configration, rather than modifing makefile?

If not possible, is it necessary to add an interface for this?

Thanks,
