[OE-core] [PATCH 01/12] tune/arm: Set -mtune instead of -mcpu

Khem Raj raj.khem at gmail.com
Wed Jun 6 21:37:17 UTC 2018 

-march option is already used to select the base architecture
therefore using -mcpu which infact will reset march+mtune can
cause conflicts, therefore setting just mtune here will ensure
that the code is optimized for the given tune as is the intention
of mcpu, however with one advantage, it will be targetting broader
march value so can be useful for pre-compiled objects where they
can be run on wider subset

This also fixed occasional conflicts like

cc1: error: switch -mcpu=cortex-a7 conflicts with -march=armv7-a switch [-Werror]

which is possible combination in some case for packages in OE
