Done now.  For x86_64 and ARM, where the latter required me to extend the 
current relocation support to some more cases.  To test the latter I used 
gawk and mpfr, for which I had to add alloca support to ARM.  So I'm 
reasonably sure that my changes don't cause regressions, but from reading 
the code there's still potential to fix more things (and of course to 
implement ARM shared libs).  One of those days ...


Ciao,
Michael.
