Generally, our host gcc version below 8.0, but cross toolchain in yocto
above 8.0, now 8.3, the option "macro-prefix-map" coming from 8.0, so if
the host gcc below 8.0, it can't unrecognized the option "macro-prefix-map".
In criu source code, the HOSTCFLAGS coming from CFLAGS:
https://github.com/checkpoint-restore/criu/blob/criu-dev/Makefile#L17
In yocto project, the CFLAGS coming from the cross toolchain, containing
the "-fmacro-prefix-map" default, so we should use the BUILD_CFLAGS, it
contains the flags that used for host building.
