The EPICS Makefile below should build a library and an IOC for linux-arm
but not for the linux-x86_64 host architecture (assuming you built Base
with CROSS_COMPILER_TARGET_ARCHS = linux-arm). You may need to adjust
the TOP variable in the first line depending on how far down the tree
this file is placed, and obviously the source filenames. The important
parts for the target-only build are the setting of the LIBRARY* and
PROD_IOC* variables.
