[gccsdk] Unable to build native RISC OS compiler

I've just tried to build the native RISC OS compiler on a Debian system

and it failed with:

 

checking whether stripping libraries is possible... yes

checking if libtool supports shared libraries... no

checking whether to build shared libraries... no

checking whether to build static libraries... yes

/home/alanb/gccsdk/gcc4/riscos/asasm/elftoolchain/configure: line 11928: syntax

make[1]: *** [ronative-riscostools-built] Error 2

make[1]: Leaving directory `/home/alanb/gccsdk/gcc4'

Any ideas how to fix this?
