Subject: [PATCH] retarget: move compat header for ARMClang prior any cmsis
 headers

Reference: CMSIS 5.8.0 known issues and https://github.com/ARM-software/CMSIS_5/issues/1211

This fixes the error about redefinition of enable/disable irq. we need compat header because of
semihosting (not yet provided in CMSIS).
