[M3devel] Update on cm3cg for x86_64 Linux

[Tony Hosking]

It seems there is an incompatibility between cm3cg built using default  
gcc (not -m32) on x86_64 Linux and the CM3 front-end targeting 32-bit  
LINUXLIBC6.  I get errors in the gcc-based backend code if I build it  
without -m32 using it to compile M3IR.  Looks like some problem with  
LONGREAL alignment.  If I build using -m32 then cm3cg works just fine  
on x86_64.  Anyway, something to watch out for.
