Siva Chandra c9e1ecd46d [libc] Adjust aarch64 startup code to reliably sniff out the start args. 
Since this now allows, the init/fini array iteration has been added in
a similar fashion to x86_64 and the corresponding test enabled.

Siva Chandra Reddy 86bebe1a90 [lib][Obvious] Fix style in a few include directives. 2022-02-16 05:57:12 +00:00
Jeff Bailey 55120aad4e Implement basic loader for Linux aarch64 
This implements a basic arm64 loader for Linux, and all the currently
enabled linker tests pass.  TLS is not implemented, and functions
using it will have undefined behaviour.  Notably, the TLS test is
currently disabled on x86_64.

Much of the structure is copied from x86_64 to allow for a refactoring
of the start code between architectures.

Tested:
ninja libc_loader_tests on aarch64-linux.
