Looking at "BaseTools/Conf/tools_def.template", the following toolchains appear supported for both ARM and AARCH64:
- CLANG35
- CLANG38

They are documented (in the same file) as:

#   CLANG35     -Linux,Windows-  Requires:
#                             Clang v3.5 or later, and GNU binutils targeting aarch64-linux-gnu or arm-linux-gnueabi
#                        Optional:
#                             Required to build platforms or ACPI tables:
#                               Intel(r) ACPI Compiler from
#                               https://acpica.org/downloads
#   CLANG38  -Linux-  Requires:
#                             Clang v3.8, LLVMgold plugin and GNU binutils 2.26 targeting x86_64-linux-gnu, aarch64-linux-gnu or arm-linux-gnueabi
#                             Clang v3.9 or later, LLVMgold plugin and GNU binutils 2.28 targeting x86_64-linux-gnu, aarch64-linux-gnu or arm-linux-gnueabi
#                        Optional:
#                             Required to build platforms or ACPI tables:
#                               Intel(r) ACPI Compiler from
