# There are 3 sysroots involved in building the final product:
#
# - toolchain sysroot -- Built when the toolchain is built.  Contains
#                        all the files needed by the toolchain.
#
# - development sysroot -- Starts as a pristine copy of the toolchain
#                          sysroot.  Intermediate build products and
#                          libraries are installed here.
#
# - final sysroot -- final executables and libraries we really want
#                    are installed here plus any additional files
#                    required from the toolchain sysroot.  The final
#                    sysroot has all of its binaries stripped.
