* Eliminate FAKE_SOURCES
* Make runtimes and projects build with the new front-end by not relying on 'llvm-gcc -c' to build a .bc file. Instead, use llvm-gcc -S -emit-llvm, then an explicit invocation of gccas. Also, don't use llvm-gcc to link .bc files together, use gccld directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25707 91177308-0d34-0410-b5e6-96231b3b80d8
