No - at least something else to begin with. A special liker script is used when building the vdsp files for x86 - and the linker script is ignored as such when embedded in a .o file with ar it seems. This is not a big suprise.
The makefile magic used for the vdso part of the kernel needs a bit more coffee than what is good for me for now... Will look at it again later.
