:*** Error code 1

:-fno-stack-protector is used sucessfully elsewhere in the build, so
:I'm betting the specification of "PATH=/usr/bin:..." is causing grief
:because the build is picking up the native compiler and not the cross
:compiler which does support the above option. That said, I wasn't sure
:whether the problem is using the native compiler or the compiler
:option (or something completely different).

    You nailed it.  It's using the wrong compiler... but it's too late
    to fix that.  I'm going to use David Rhodus's patch in the release
    tree instead.
