When we request a thumb build on a non-thumb-only target, we hand compilation to a script that tries to build everything as thumb, falling back to non-thumb arm mode if the thumb build fails. In order for this to work, the compiler flag -mthumb-interwork is required. Move this definition out of the thumb-cc script, and into the configure script (ie along with the other target-specific definitions) Change-Id: Idc1f8caa088dbbf710b169b272de61cc0b7c9ca6
