# GCC's libgcc generates source files which depend on generated
# header files, which means we have to generate our tools set before
# we can build libgcc.  The toolset is normally built afterwards.
#
# XXX for the world stage we could theoretically use the cc_tools generated
# in the btools stage, but it's easier to regenerate them.
#
# Assumed to be built prior to this makefile:
#   gnu/usr.bin/cc47/cc_prep
#   gnu/usr.bin/cc47/cc_tools
#   gnu/lib/gcc47/csu
