add musl-clang, a wrapper for system clang installs
musl-clang allows the user to compile musl-powered programs using their already existent clang install, without the need of a special cross compiler. it achieves this by wrapping around both the system clang install and the linker and passing them special flags to re-target musl at runtime. it does only affect invocations done through the special musl-clang wrapper script, so that the user setup remains fully intact otherwise. the clang wrapper consists of the compiler frontend wrapper script, musl-clang, and the linker wrapper script, ld.musl-clang. musl-clang makes sure clang invokes ld.musl-clang to link objects; neither script needs to be in PATH for the wrapper to work.
