Fix ARM SwapEndian on armv6+ for compilation with FPC 2.6

Browse Source 
We're currently using rev for armv6+, but FPC 2.6 could not handle the
instruction. So if somebody wants to build trunk it can't be for armv6+.

We'll circumvent the problem by always using the the generic code when
build with FPC 2.6.
