sys/targets: allow users to override hardcoded cross-compilers
Currently, cross compiler names are hardcoded for each OS/arch combo.
However, toolchain tuples differ, especially when using vendor provided
toolchains or building with Yocto. Allow users to specify the cross
compiler for an OS/arch combo using SYZ_CC_<os>_<arch> environment
variables.
