gcc-target.inc: configure gcc for armv7ve targets to default to armv7ve

gcc-target.inc: configure gcc for armv7ve targets to default to armv7ve

Originally these ARM specific EXTRA_OECONF options were applied to
both gcc for the target and gcc-cross. That lead to a compromise
being made: gcc on the target was configured to default to an ARM
architecture which was at least compatible with the target (but not
necessarily an exact match) and gcc-cross was configured default to
armv7a for both armv7a and armv7ve (to avoid gcc-cross rebuilds when
switching between the two).

However, when these ARM specific EXTRA_OECONF options were moved from
gcc-configure-common.inc into gcc-target.inc (ie they were made to
apply only to gcc on the target) the compromise no longer needed to
be made.
