%description

This is a Cross Compiling version of GNU GCC, which can be used to

compile for the %{target} platform, instead of for the

native %{_arch} platform.

This package is based on the CodeSourcery %{cs_date}-%{cs_rel} release,

which includes improved ARM target support compared to the corresponding 

GNU GCC release.
