clang: Remove unintended dependency on gcc-runtime

Commit a494bbb6ec44 ("clang: support android runtime") introduced an
unrelated change causing builds with RUNTIME="llvm" and COMPILER_RT not
set to get a dependency on virtual/${TARGET_PREFIX}compilerlibs.

This is clearly unrelated to addition of support for android runtime,
and causing unwanted depdencies to gcc-runtime for LLVM builds.
