Note that putting this change into that file will actually add the -m32
flag to /all/ builds run when EPICS_HOST_ARCH is linux-x86, no matter
what target architecture is being compiled at the time. You shouldn't
have to make this change on recent versions of EPICS Base anyway since
the -m32 flag is already present in the CONFIG.Common.linux-x86 file.

Note that the message you referred to dates back to 2008 and Till's
change is dated 2006; we have made many changes to the build system
since then, so I recommend that you remove that change even though it
may seem harmless at the moment.
