Thanks Nick, that worked OK. One last problem, I hope it isn't fatal:
the mmap which the rtld uses to map the loadarea section marks it as
"rwxp", but this will cause allocation failures on machines with no
overcommit. I want it to be just "r--p".

I've read the gas manual and it looks like the only section flags in ELF
binaries do not allow you to mark a section as being mapped readonly.
Please tell me this isn't the case! I'm sure it must be wrong, as there
are sections that are clearly being mmaped with (PROT_READ), I just
can't see how it's done.
