[uClibc][armeb] recvfrom fails with EFAULT when from, fromlen are not NULL

["Alon Bar-Lev" <alon.barlev@xxxxxxxxx>]

Hello,

I opened a bug in uClibc [1], but I think maybe someone is interested to help.

When running a simple UDP listener on big endian system, the program
blocks until a message is received and then returns with EFAULT, this
happens when from structure needs to be stored.

glibc works as expected.
glibc, uclibc work as expected on armel.

So the issue may be related to the big endian... But I cannot figure
it out from the sources.

Does someone use big endian system with uClibc?

Maybe someone know the difference between the endianness of the ARM EABI?

Thank you,
Alon Bar-Lev.
