The following defconfig produces the problem:

BR2_x86_pentium_mmx=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y
BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.net/toolchains/tarballs/br-i386-pentium-mmx-musl-2017.11-rc1.tar.bz2"
BR2_TOOLCHAIN_EXTERNAL_GCC_6=y
BR2_TOOLCHAIN_EXTERNAL_HEADERS_3_12=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM_MUSL=y
# BR2_TOOLCHAIN_EXTERNAL_HAS_SSP is not set
BR2_TOOLCHAIN_EXTERNAL_CXX=y
BR2_INIT_NONE=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_DAQ=y
BR2_PACKAGE_LIBDNET=y
BR2_PACKAGE_LIBNETFILTER_QUEUE=y
# BR2_TARGET_ROOTFS_TAR is not set

Basically, musl doesn't have any <sys/unistd.h>. The package should
include just <unistd.h>. Even on glibc, <sys/unistd.h> is just doing
#include <unistd.h>.

Best regards,

Thomas
