. 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) Change-Id: If5c44ef766f5b4fc4394d4586ecc289927a0d6eb
