[Gustavo Zacarias]

It's broken as well, wants to emit v9 asm.

Applied, but shouldn't we simply deprecated eglibc ? The latest eglibc
release was 2.19, and glibc has already made two releases (2.20 and
2.21) since then.

Unfortunately eglibc 2.18 is the only (e)glibc that's good for powerpc
SPE at the moment (that does hard-float), so that would mean leaving
only uClibc for that scenario.

Well if nobody cares about powerpc SPE in upstream glibc, using uClibc
will be the only solution.

From what i've read there was a effort to get soft-fp going for that
which makes sense because E500v1 is only single-precision and E500v2 is
double, to make them ABI compatible.
I'll dig and get back on it since keeping eglibc around might not be a
good idea long-term.
Regards.
