All ARM version 7 systems support a vector hardware floating point unit and
have the ability to run using the hard floating point ABI (aapcs-vfpv3-d16).
This is the only configuration we support as a v7 target, so we force the
use of hard floating point. This prevents e.g. packages being built with
a armv5tel target on an armv7 system without explicit intent.

- as per http://fedoraproject.org/wiki/Features/ArchitectureSupport
- set 32 bit intel build arch to i586 on compatible hardware
- set 32 bit sparc build arch to sparcv9 on compatible hardware
- add missing armv7l arch
- set the default build arch to match fedora arm build target
