Description Chester Lin 2019-09-04 06:10:46 UTC 
The error message:

net/bpfilter/main.c:3:10: fatal error: sys/uio.h: No such file or directory
    3 | #include <sys/uio.h>
      |          ^~~~~~~~~~~
compilation terminated.
make[2]: *** [scripts/Makefile.host:107: net/bpfilter/main.o] Error 1
make[1]: *** [scripts/Makefile.build:490: net/bpfilter] Error 2
make: *** [Makefile:1087: net] Error 2

It happened while cross-compiling the Linux kernel [ARCH=riscv] on x86_64, which was based on current stable branch (v5.2.11) and the following files under openSUSE:Factory:RISCV -->

kernel-source/patches.addon/*.patch files
kernel-source/config.tar.gz -> config/riscv/default

My cross-compiler packages are as below, and both cross-riscv64-elf-gcc and cross-riscv64-gcc can experience this issue:

The cross compiler only supports a freestanding environment.

Right, and sys/uio.h comes from glibc.
