I got to the point of trying a build that happens to have
tried to use this code. It failed, reporting:
--- libc.so.7.full ---
building shared library libc.so.7
cc: error: invalid linker name in argument =
'-fuse-ld=3D/usr/local/bin//usr/local/powerpc64-unknown-freebsd13.0/bin/-l=
d.bfd'
*** [libc.so.7.full] Error code 1
So I switched the code to:
.if defined(CROSS_BINUTILS_PREFIX)
LD_BFD=3D${CROSS_BINUTILS_PREFIX}ld.bfd
.else
LD_BFD=3D${OBJTOP}/tmp/usr/bin/ld.bfd
.endif
With that in place, the build completed.
