Message:

Unify compiler handling a bit.

Most compiler flags have been changed from GCC-specific to "common",
since code might build but not work properly without them.
Clang still rejects some of the flags, but at least we can see
the incompatibilities now.

Explicit —target flag was removed from clang, in favor of using clang
through a target-specific symlink. This allows clang to automatically
find correct assembler and linker, if it needs to.

Additionally, assembly language files are now compiled using $(CC)
whether or not they need the preprocessor. This allows clang to build
.s files using its integrated assembler.
