[OE-core] [PATCH] tune/armv7: Add -mthumb to TUNE_CCARGS

[Khem Raj]

armv7 is least common denominator of armv7-a
armv7-m and armv7-r and armv7-m does not support
ARM instructions but only thumb2 instruction set
which means armv7 when chosen will complain if
code is compiled in arm mode which is default
in OE if not specified other wise

Fixes errors like below

error: target CPU does not support ARM mode
