Michał Górny dd153de4f0 CMakeDetermineASMCompiler: arg-split ASM* env var like CC
Split the arguments off of the `ASM${ASM_DIALECT}` environment variable
as is done for `CC` and other compiler variables. This fixes using CMake
when `ASM*` is used to pass additional target flags, e.g. when one uses
`ASM=${CC}`.
