Recapitalise ARMvX{-Y} to ArmvX{-Y}

Yes it looks weird, but this is how Arm write it now.

I left ARM64 alone, because it's a Microsoft/Apple term but not an Arm term (they have Armv8-A and Armv9-A architectures, which say that A64 instructions are executed when in the Aarch64 state), and I don't want to get into that, especially for a Tier 1 target.

+Target for cross-compiling Linux user-mode applications targeting the Arm BE8 architecture.
 
 ## Overview
-BE8 architecture retains the same little-endian ordered code-stream used by conventional little endian ARM systems, however the data accesses are in big-endian. BE8 is used primarily in high-performance networking applications where the ability to read packets in their native "Network Byte Order" is important (many network protocols transmit data in big-endian byte order for their wire formats).

BE8 is used primarily in high-performance networking applications where the ability to read packets in their native "Network Byte Order" is important (many network protocols transmit data in big-endian byte order for their wire formats).
 
 ## History
-BE8 architecture is the default big-endian architecture for ARM since [ARMv6](https://developer.arm.com/documentation/101754/0616/armlink-Reference/armlink-Command-line-Options/--be8?lang=en). It's predecessor, used for ARMv4 and ARMv5 devices was [BE32](https://developer.arm.com/documentation/dui0474/j/linker-command-line-options/--be32). On ARMv6 architecture, endianness can be configured via [system registers](https://developer.arm.com/documentation/ddi0290/g/unaligned-and-mixed-endian-data-access-support/mixed-endian-access-support/interaction-between-the-bus-protocol-and-the-core-endianness). However, BE32 was withdrawn for [ARMv7](https://developer.arm.com/documentation/ddi0406/cb/Appendixes/Deprecated-and-Obsolete-Features/Obsolete-features/Support-for-BE-32-endianness-model) onwards.
