Sources and patches
-------------------

The upstream binutils tree is supplied via the binutils-source binary
package.  At build time we extract /usr/src/binutils/binutils-*.tar.xz
into the binutils/ directory; that tarball is shipped post-patch (the
Debian quilt series in /usr/src/binutils/patches/ has already been
applied to the source it tars up), so we do not re-apply it here.

On top of the unpacked tree we then apply, in lexicographic order, any
patches found in debian/local-patches/[0-9]*.patch using `patch -p1`.
This directory is reserved for changes that are local to this
cross-toolchain packaging, typically backports of in-flight upstream
work needed by the Raspberry Pi Pico Hazard3 core (RP2350) that have
not yet landed in a Debian binutils release.
