# Build a more advanced cross compiler, including thread support and uClibc++,
# built --with-shared (which produces libgcc_s.so), statically linked
# against uClibc on the host (for portability), and including the $TARGET-ldd
# and $TARGET-ldconfig utilities.

# Building this requires two existing (simple) cross compilers: one for
# the host (to build the executables) and one for the target (to build
# the libraries).

# This is a simple wrapper for native-compiler.sh, we re-use the canadian
# cross infrastructure in there to build a very similar compiler.
