clang: ToolChains/Gnu.cpp: search also in lib32

* in some strange multilib configs we build lib32-image where
  32bit libs are in /usr/lib32 and 64bit in /usr/lib64 but in such
  setup the clang search for GCC candidate installation doesn't
  check lib32 directory in sysroot and fails to find the installation

  X86LibDirs was already searching in lib32 for very long time:
  https://github.com/llvm/llvm-project/commit/621fed5f5a051a0333415aaed75b8f2ed2350dbd
  but ARMLibDirs didn't include it for some reason.

* if we don't add lib32 for arm in getOSLibDir(), then it will
  find -lgcc, crtbeginS.o, crtendS.o, but still fail to find
  -lgcc_s, -lc, Scrt1.o, crti.o, crtn.o

* fixes lib32-compiler-rt build failure:

-- Configuring incomplete, errors occurred!
