I’m fine with dropping things on the build farm; it’s just about
modifying machines-for-berlin.scm in maintenance.git.  Any takers?  :-)

The above would override the default CFLAGS in Autoconf-generated
configure scripts (which is “-O2 -g”).  So we’d have to be cautious.
But I think a global solution is preferable to adding
-D_FILE_OFFSET_BITS=64 to tens of packages.
