Kernel v4.14 and newer contain the following in their Makefile:
HOST_LFS_LDFLAGS := $(shell getconf LFS_LDFLAGS)
HOSTLDFLAGS := $(HOST_LFS_LDFLAGS)
This breaks our menuconfig, because it can no longer find ncurses if its
not on the host machine. This can be seen in linux-yocto-dev, for
example:
[clsulliv@clsulliv build]$ bitbake virtual/kernel -c menuconfig
GEN ./Makefile
HOSTLD scripts/kconfig/mconf
/home/clsulliv/yocto/poky/build/tmp/hosttools/ld: cannot find -lncurses
/home/clsulliv/yocto/poky/build/tmp/hosttools/ld: cannot find -ltinfo
collect2: error: ld returned 1 exit status

Fix this by setting HOSTLDFLAGS to ${BUILD_LDFLAGS} in our
'make menuconfig' command.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
