Selftests need kernel headers and glibc for compilation. In compilation
of selftests, uapi headers from kernel source are used instead of
default ones while glibc has already been compiled with different header
files installed in the operating system. So there can be redefination
warnings from compiler. These warnings can be suppressed by using
-isystem to include the uapi headers.
