Tamar Christina 61ddc7a436 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.

Tamar Christina cd26662dc5 Previous patch to support nosys.specs accidentally broke validation specs because ARM_RDI_MONITOR was never passed to the build rule for crt0. 
This fixed the compile for nosys and validation specs
but nosys won't run because of existing limitations to
aarch64's syscalls.c, it requires semihosting to get
commandline arguments and heap info without having a
fallback method as ARM does.

Tamar Christina bfa3bbcf33 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.
