build: Clean up build toolchain (and use musl for libc)
Using musl is required to match several functions that use <math.h>
floating point functions like isnan.
This also removes a dependency on devkitA64. We previously only needed
it because Clang insisted on using GCC to link the final executable
owing to the use of a "bare metal" target like aarch64-none-elf.
We can make Clang invoke the linker itself by using a Linux target.
