binutils/spec.binutils.cross

# Note - this is an rpm spec file, but it has been renamed in order to avoid
# conflict with the real binutils.spec file.
#
# Its only use is intened to be to build a cross-binutils rpm by installing it
# into an rpmbuild tree where the binutils source rpm has already been placed.
# It should be run as:
#
#    rpmbuild -bb spec.binutils.cross

%description
Provides a collection of cross built binutils for the targets
supported by RHEL (aarch64, i686, ppc64le, s390x).

# Note - this list assumes that we are building on an x86_64-linux-gnu host.

%build

# Build each set of cross binutils individually.

# Then unpack them ...
# FIXME: There are two possible destinations for built rpms...
# FIXME: Handle this more cleanly than the duplicated for loops below.
