Hi, friends in EPICS community.

Recently I got Apple Macbook pro with Apple M1 CPU, running macOS Big Sur.
Today, I successfully built fat binaries for EPICS R7 base software.

So far I tested softIOC and ca_get command in both x86_64 and arm64

architectures

using clang/clang++ compilers from Apple.

To build these binraries, I just needed to modify Makefiles as shown below.

1) In base/configure/os/CONFIG_SITE.Common.darwin-x86, set the

ARCH_CLASS variable as

	ARCH_CLASS = x86_64 arm64

2) Rebuild "libreadline.dylib" in /usr/local/lib ( or where you

installed it) as a fat binary.

To build it,  I modified  readline-8.1/Makefile:

 CFLAGS = -arch x86_64 -arch arm64 -g -O2 -Wno-parentheses

-Wno-format-security

and readline-8.1/shlib/Makefile:

 SHOBJ_LDFLAGS = -arch x86_64 -arch arm64 -dynamiclib -dynamic

-undefined dynamic_lookup
