2 powerpc targets fail with following message

RUNNING ALL TESTS
bad MINSIGSTKSZ value at byte 2: rust: 8 (0x8) != c 16 (0x10)
thread 'main' panicked at 'some tests failed', /checkout/target/powerpc-unknown-linux-gnu/debug/build/libc-test-4790929c323c3f02/out/all.rs:11
note: Run with `RUST_BACKTRACE=1` for a backtrace.

could you please help me to understand what does this error mean?

[alexcrichton]

Oh that just means that the value for the constant is different on powerpc than is what's currently defined. You'll want to update the constant's value on powerpc to fix the message. Right now it's just saying that the value a byte 2 differed, in Rust is was defined as 0x08 and in C it's 0x10

[anatol]

I can change it to match the system libc. But it is weird it uses a value different from Linux kernel uapi. The const defined as 2048 there.
