[PATCH] powerpc: Use FLAG_ELF_LIBC6 for 32-bit known libraries

[Florian Weimer]

* Lucas A. M. Magalhaes:

> libc.so.6 don't depend on itself or on libm it will be flagged as
> FLAG_ELF instead of FLAG_ELF_LIBC6 as expected.

I would like to defer review of this patch to the POWER maintainers, sorry.
(I just spotted a typo in the first version.)

Thanks,
