I think Florian's suggestion from that discussion is a good idea: generate 
a makefile equivalent of abi-versions.h, so that you can write 
conditionals in makefiles that are equivalent to SHLIB_COMPAT conditions 
in C code.

Obviously this is not specific to ILP32 so should be proposed for master 
independent of ILP32 - it's just as useful for other new ports such as 
RISC-V (kernel port hopefully ready for upstream in the not too distant 
future) or ARC (kernel port already upstream).
