   5 """NaCl gcc wrapper that presents glibc and newlib as a single
   6 toolchain.
   7
   8 This wraps the newlib and glibc compilers and allows users
   9 to choose which one they really want by passed in --glibc
  10 or --newlib on the command line.
  11
  12 We need this when using gyp to generator build files since
  13 gyp only support one target toolchain and one host toolchain
  14 (for now).
