I haven't checked the current binary versions, but previously default
settings and making sure to use similar (cross-)toolchain versions
achieved bit-identical results.

As mentioned in [1], I'd be willing to maintain or co-maintain a
firmware packages for carl9170, but this would need coordination (and
an ack) from you (as linux-firmware maintainer) and the kernel-team,
given that driver and firmware are both under development (and require
minimum versions of each). My preliminary packaging[2] (which I'm using
personally for quite a while) does build the cross-toolchain from
Debian's source packages for gcc/ newlib/ binutils during the package
build process[3]. This procedure is certainly not nice and needs
adapting whenever gcc changes (minor) versions, but it does build
everything from source - adding a formal sh-2/ newlib based
cross-toolchain would imho be overkill, especially as this wouldn't
be useful for anything else.

using build concurrency is recommended, as this significantly
reduces the build time for the cross toolchain.
