[En-Nut-Discussion] Parameters for the linker

[Ole Reinhardt]

Hi Uwe,

looks like your latest changes are not compatible with older GCC
versions. After an update to 5.2 / binutils 2.25.x everything works fine.

It might be an idea to keep old-style linker scripts for those who do
not yet have installed the latest toolchain?

Best regards,

Ole
