Parts of the EPICS Base build need to run programs that have just been
compiled (i.e. built for the host), which is why we have to distinguish
between the host architecture and the target architecture so much in the
build system.

You should be able to just set CROSS_COMPILER_TARGET_ARCHS in your
configure/CONFIG_SITE file and then edit the
configure/os/CONFIG_SITE.linux-x86.linux-arm file to specify the GNU_
vars for your compiler.

It is only necessary to set CROSS_COMPILER_HOST_ARCHS if you compile the
same Base installation on multiple host architectures but only one of
them has the cross-compiler.
