UNRESTRICTED | ILLIMITÉ

Ran into a problem when trying to cross-compile an EPICS application for the ARM architecture under a Linux x86_64 host.  My build created both the x86 and x86_64 binary, but would not create the ARM.  I eventually change the application makefile:

PROC_HOST = myApplication

to

PROC = myApplication

This caused ARM version to compile, but it failed due to missing libraries in the base, specifically asHost and dbStaticHost.  Looking at the makefile for those library, I noticed that it had

LIBRARY_HOST = dbStaticHost

and

LIBRARY_HOST = asHost

These are the only two libraries from the EPICS base I found that define the target using the LIBRARY_HOST (macro?) instead of LIBRARY.

I changed both of these to LIBRARY, recompiled the EPICS based, then successfully recompiled the ARM version of my application.

Is there a reason why these two libraries are defined as LIBRARY_HOST instead of just LIBRARY?
