. bitcode fixes
. switch to compiler-rt instead of netbsd libc functions
or libgcc for support functions for both x86 and arm
. minor build fixes
. allow build with llvm without crossbuilding llvm itself
. can now build minix/arm using llvm and eabi - without C++
support for now (hence crossbuilding llvm itself is turned off
for minix/arm)

Do not build clang and llvm libraries with debug symbols, when built as
a cross-compilation tool.
This saves a lot of space (about 4G), and hopefully also some
compilation time.

Allows instrumentation of Minix components using LLVM passes from
"llvm-apps" repository
In addition, the change does the following:
1. Move releasetools/generate_gold_plugin.sh to minix/llvm
2. Move external/bsd/llvm/passes to minix/llvm/passes
3. libLTO.so, LLVMgold.so and WeakAliasModuleOverride.so files
now get installed in minix/llvm/bin
In case of installation of both clang and GCC, we want to be able to
switch which one is the default by adapting the cc, c++ & cpp symlinks.
The default behaviour implemented here is to prefer clang over gcc if
they are both installed.
