# WARNING: This package can NOT be built using the CodeSourcery multilib
#          toolchain, it will NOT function as expected!  This is due to#
#          limitations in the gcc configuration system; the e500v2 cross
#          toolchain on the build system MUST be configured identically
#          to the final toolchain (which is this package).  Stevep

# target is needed.  This should really be defined in the config
# area of ltib, and not done in the toolchain spec files.
# For now we assume that the optimised target can be derived by
# stripping the trailing "-" off the toolchain prefix, but this
# will not be true for all cases, eg when using uClibc toolchains.
