Subject: [PATCH] Dont specify -march explicitly
it assumes armv7-a for all armv7 based machines but that may
not be true e.g. machines based on armv7ve and cortexa-7
it causes conflicts in OE builds because it specifies -march
in recipes anyway so this is redundant in CMakeLists.txt
Fixes
| cc1: warning: switch -mcpu=cortex-a7 conflicts with -march=armv7-a switch
| cc1: warning: switch -mcpu=cortex-a7 conflicts with -march=armv7-a switch
