Subject: Changes to support cross-compiling LLVM. The GenLibDeps.pl script
 needs to have a compile-host version of "nm", not build-host. In order to
 effect this we must use autoconf to determine the correct "nm" to use and
 propagate that through the makefiles, through llvm-config and finally to
 GenLibDeps.pl as an optional argument. Patch contributed by Anton
 Korobeynikov. Thanks!
