%description
This is the RISC-V fork of the GNU cross-compiler toolchain.  It
includes binutils and GCC.

%setup -q -n %{name}-@COMMIT@


%build
# This only works if you build in a build subdirectory.
mkdir build

# The ordinary Makefile downloads upstream GNU packages.  Instead we
# provide these as local files.  Note this is "DISTDIR" not "DESTDIR".
export DISTDIR=%{_sourcedir}

# Since the Makefile installs as it goes along, clean the buildroot
# now (instead of at the top of install).

# We need to use the tools we built as we go along.

# The 'make linux' rule builds GCC linked against glibc (instead of
# newlib).
