From: Alexis Lothoré (eBPF Foundation) <alexis.lothore@bootlin.com>

commit 93cf4e537ed0c5bd9ba6cbdb2c33864547c1442f upstream.

test_select_reuseport_kern.c is currently including <stdlib.h>, but it
does not use any definition from there.

Remove stdlib.h inclusion from test_select_reuseport_kern.c

[shung-hsi.yu: Fix compilation error mentioned in footer of Alexis'
patch with newer glibc header:

[...]
CLNG-BPF [test_progs-cpuv4] test_select_reuseport_kern.bpf.o
In file included from progs/test_select_reuseport_kern.c:4:
/usr/include/bits/floatn.h:83:52: error: unsupported machine mode
'__TC__'
83 | typedef _Complex float __cfloat128 __attribute__ ((__mode__
(__TC__)));
| ^
/usr/include/bits/floatn.h:97:9: error: __float128 is not supported on
this target
97 | typedef __float128 _Float128;

I'm not certain when the problem starts to occur, but I'm quite sure
test_select_reuseport_kern.c were not meant to be using the C standard
library in the first place.]
