Adds the needed build system changes in order to compile and create the new libraries for Semihosting v2. This uses the new recursive build target in multi-build.in For AArch64 no new spec files are needed but the makefiles are modified to keep them in sync with the ARM ones.

Fix crt0 overwriting. On AArch64 we currently always link in crt0 regardless of if another one is being provided by something else, like rdimon.a. This was never an issue before as nosys was not supported on AArch64. This updates the specs to supply a different crt0 when a semihosting call is required.
