"""NaCl gcc wrapper that presents glibc and newlib as a single
toolchain.

This wraps the newlib and glibc compilers and allows users
to choose which one they really want by passed in --glibc
or --newlib on the command line.

We need this when using gyp to generator build files since
gyp only support one target toolchain and one host toolchain
(for now).
