CFLAGS += -Wcast-align

to global_config after configure generated it

Aaaand ... it seems that our python code really generates  c files with loads of those cast-align warnings, but some core files have them too ...

I honestly do not know how to properly fix this :(

and so on ...

They are harmless on x86/arm, but surely kills program on mips64/sparc (and may be Alpha).
