The bionic libc test test_seteuid fails

[haozhun]

Description

The test_seteuid tries to seteuid to an arbitary user id (9999 in this case). And then set it back to 0.

It fails upon first call to seteuid, with trapframe printed. See "current result" for details.

Reproduce steps

cd ~/ucore_plus/ucore 
make ARCH=arm BOARD=goldfishv7 defconfig
make sfsimg
make kernel
./uCore_test -s bionic -w 15 -t 45 -f src/user-ucore/testspecs/test_seteuid.testspec 

Current result

kernel_execve: pid = 4, name = "/bionic-test/test_seteuid".

You can simply remove this line. Issues are issues and we may not care
where it comes from.

Description

Something goes wrong according to the log from the serial console and the
test fails.

Please be more detailed. I think you should have read the code of the test
and know what it tries to do and what it expects. And you have the console
log and knows what's the sympton. Please add these info in the description.

Reproduce steps

./uCore_test -s bionic -w 15 -t 45 -f
src/user-ucore/testspecs/test_seteuid.testspec

mmm... Could you please add the steps involved to reproduce the issue on a
fresh-pulled repo? The steps of building should also be included so that we
know what config you are using.
