build: improve diagnostics for unrecognized toolchain tools
Up until recently the build system accepted an arbitrary value for `AS`
and, unbeknownst to anybody, was simply not making use of it. Recent
feedback has revealed that a number of contributors have `AS` explicitly
configured to use the GNU assembler, which is not a supported assembler,
and this breakage has yielded some cryptic error messages, e.g.:
aarch64-none-elf-as: unrecognized option '-x'
This change introduces human-readable diagnostics to help developers
with diagnosing unsupported toolchain tools:
The configured AArch64 assembler could not be identified and may not
be supported:
aarch64-none-elf-as
The default AArch64 assembler is:
aarch64-none-elf-gcc
The following tools are supported:
- Arm® Compiler for Embedded `armclang`
- LLVM Clang (`clang`)
- GNU GCC (`gcc`)
The build system will treat this assembler as GNU GCC (`gcc`).
