build: overhaul wrapper script system for multiple wrapper support
this overhauls part of the build system in order to support multiple toolchain wrapper scripts, as opposed to solely the musl-gcc wrapper as before. it thereby replaces --enable-gcc-wrapper with --enable-wrapper=..., which has the options 'auto' (the default, detect whether to use wrappers), 'all' (build and install all wrappers), 'no' (don't build any) and finally the options named after the individual compiler scripts (currently only 'gcc' is available) to build and install only that wrapper. the old --enable-gcc-wrapper is removed from --help, but still available. it also modifies the wrappers to use the C compiler specified to the build system as 'inner' compiler, when applicable. as wrapper detection works by probing this compiler, it may not work with any other.
