Using gcc to generate code snippets is a *great* idea!
This makes it really easy to port; I've already got it
running on s390 ...
A couple of minor observations:
- What do you need the linker scripts for? Is it only to choose
a non-standard offset? If so, I guess it would be less error-
prone to use the currently installed scripts ('ld --verbose')
and just change the offset using sed or so ...
- The test-i386 case gives differing results (even on i386)
for several sh[lr]dw cases and for sin(2.0) ...
- syscall.c would refuse to build due to prototype mismatch;
this patch fixes it:

B.t.w are shared libraries supposed to work already?
Thanks,
