Hi Thomas,

I am not sure what you mean by "external toolchain" here since this is a
problem with the buildroot toolchain as well. I probably don't
understand the solution you propose. This is a "quick and dirty" fix.
The ideal solution to this problem would be to fix the build systems to
use "gcc" instead of "ld" for linking.
