Subject: [PATCH] use appropriate -march/-mcpu/-mfpu for ARM test apps

Ensure that test apps in none/tests/arm are compiled with appropriate
-march/-mcpu/-mfpu flags to support the instructions being tested.
The aim is to build all tests, even ones which may not run correctly
on all target CPUs.

For tests requiring armv7ve instructions, ensure that we set both
-march=armv7ve and -mcpu=cortex-a15 (since some TUNE_CCARGS may set
-march=armv7-a and adding -mcpu=cortex-a15 alone is not enough to
over-ride that).

See similar cases in none/tests/arm/Makefile.am
