The LLVM CMake build system generates and uses llvm-config where it is
required (MSVC++ can live without it). This means that GenLibDeps.pl is
invoked for building llvm-config.

Maybe there are some such desynchronizations. Please report them and
I'll fix them.
On this specific case, IIRC, MinGW chokes if asmprinter is not on the
list of components. This may be another consequence of the malfunctoning
of llvm-config/GenLibDeps.pl on MinGW/MSYS.
