Ralph is right, only ASYN should be defined in configure/RELEASE, EPICS_HOST_ARCH should be defined as an environment variable.

Well...

While definitions of external modules like ASYN should always go into
the configure/RELEASE file (it is named RELEASE because it defines the
exact releases of external modules that you are using), EPICS_HOST_ARCH
is meant to be set in the environment.
While setting it in configure/RELEASE might work, the host architecture
is rather a property of the host than a definition of an external module.

As soon as you put your sources on a network drive and compile it for
multiple host architectures inside the same structure, setting the host
architecture in configure/RELEASE is obviously not a good idea.
