We handle things rather differently.  For concreteness, let us consider
two machines: "larry", a VAX, and "apollo", a Sun.  We have a directory
containing source to a program, say "foobar".  We wish to have only one
copy of this source and build both binaries from it.

Then one machine, say larry, has all the source in a directory
somewhere.  In the example, this would most likely be
/local/src/bin/foobar (that being our convention).  Then apollo will
have a distinct /local/src/bin/foobar containing one symbolic link per
source file, these links pointing to the corresponding files on larry.
Then the source files are perforce in sync, but the two machines have
distinct directories so that make, cc, etc don't get confused.  Some
programs will share their Makefile as well; some will need slightly
different Makefiles.  Details.

Works fine for us.  (Don't know how well it would work if the machines
were in different timezones.  Might have to wait N hours before running
the make on the other machine.  But how often do you nfs such machines
together?)
