 The error actually pertains to the compilation of host/buildvm_asm.o, which is
a host file not a target file. It helps to debug this kind of thing with
BR2_JLEVEL=1...

 It looks like there is something wrong with your system's toolchain
installation. There really should be a /usr/include/asm/errno.h. In a multilib
installation, asm is typically a symlink to <arch>/asm. Is it possible that this
symlink got removed by a botched package install?
