tools: Detect A-profile ARM cores for hosted and sim builds
The only v7-a targets we have are built using the androidndk (with gcc
4.9) but it is possible to perform "self-hosted" builds for eg the
simulator or the sdlapp.
Where this gets messy is the considerable amount of inline arm
asm we have.
Native builds will need considerably more work to support
v7-a processors, but we have to start somewhere.
(Note that this contains parts of commit 508bfabe8, which had to
be reverted due to breakage)
