Ah, I missed the "custom compiler" context. In that case, maybe just
tweak the internal linker scripts? They're generated from
<eachtarget>.sc in the source, e.g. binutils-2.23/ld/scripttempl/ .
Tweaking templates causes your customisations to be not only fully
integral to the toolchain, for the specified targets, but also more
customisable than a generic INSERT. (And very easy)
