That would work (if you put those at the end of the file) as long as
you are only building for the host architecture. If you will need to
be able to cross-build for IOCs of other architectures and/or
operating systems the settings for your particular host target
should be added to the file
configure/os/CONFIG_SITE.Common.<host-arch> or
configure/os/CONFIG_SITE.<host-arch>.<host-arch> where
<host-arch> would be linux-x86_64 for 64-bit Linux on Intel or
amd64 hosts. Configuring builds for any cross architectures is more
complicated.

Subject: how to configure compiler version
Dear all,
If there are three versions of gcc installed on the OS, how should I
set up epics to use a particular version of gcc. Right now I find that
/usr/bin/gcc is always used.
